Since Mermails are finally and officially out I’ll post my decklist along with some comments and strategy, but I don’t have that much time so I guess it’ll be a bit shorter than my usual deck reviews.

I’ve tried many different builds, like the pure Mermail build, the Genex Undine build, the Mermail Atlantean Hybrid build, the Forgotten Continent build, but found the Mermail Atlantean Hybrid build still the best.

Strategy and Explanation

First I’ll introduce you the cards that I used or didn’t use with some pics and explanation.

Mermail – Abysslinde

This is your main searcher/special summoner of your deck and she’s just overpowered, as she can summon all of your mermails even Megaloabyss (!) depending on the situation. Too bad that most of the Mermail effects can only be activated once per turn. Linde combos well with Torrential Tribute, giving you a powerful Megaloabyss, while destroying your opponents monster. You will always want to start with her in hand as she will always give your opponent headaches if she can resolve her effect. Good thing is that she can be searched by Pike.

Mermail – Abyssgunde

This is your tech to revive your Mermails from grave. Her effect activates when she’s discarded to the grave and her wording makes her not miss the timing regardless what. You have to remember what I wrote before:

A card will miss its timing with a certain wording when there’s a part of an effect still resolving while the condition to trigger the certain cards effect is met (sounds confusing, I know, but I’ll explain it with an example).

The wording is: – When this card is destroyed/discarded to the grave, you can … (or something similiar).

The important thing here to notice is that it will only resolve its effect if you can resolve it the moment it is destroyed and the effect that destroys or discards doesn’t have another part yet to resolve after destroying or discarding, as it isn’t a mandatory effect, but an effect you can choose to activate or not. If there is something like this, your card will miss its timing.

Lightpulsar Dragon’s effect:

  • When this card is sent from the field to the Graveyard: You can target 1 Level 5 or higher DARK Dragon-Type monster in your Graveyard; Special Summon that target.
  • Example: On your field: Lightpulsar Dragon (LPD); In your grave: Red-Eyes Darkness Metal Dragon (REDMD). You attack your enemy’s facedown Ryko. Ryko’s effect activates and the opponent decides to destroy your LPD.
  • Normally when destroyed you could summon your REDMD from grave, but Ryko’s effect still resolves and mills 3 cards to the grave. Therefore you missed the moment LPD was destroyed and LPD’s effect can’t resolve, as the last thing happened was milling 3 cards.
  • The same thing happens if your opponent uses Soul Taker (Effect: Destroy 1 face-up monster your opponent controls. Then, your opponent gains 1000 Life Points.) to destroy your LPD. The last thing that happens would be you gaining 1000 LP and not the destruction of LPD, therfore you will miss the timing to summon a DARK Dragon from your grave.
  • But don’t let yourself get tricked, if there are multiple effects that triggers on destruction or discard, your effects with the “When” wording won’t miss the timing.
  • Example: You play Dark Hole, your opponent has an Elemental HERO The Shining (Effect: When this card is sent from the field to the Graveyard: You can target up to 2 of your banished “Elemental HERO” monsters; add those targets to your hand.) on the field, while you have a LPD with a DARK Dragon in grave.
  • Both of them have a not-mandatory “When” effect that triggers on destruction, so the effects will activate like this:
  • As you are the Turn Player and both effects are not-mandatory, your LPD effect will be Chain Link 1, The Shining’s effect will be Chain Link 2, therfore The Shining’s effect resolves first
  • You might think that LPD now misses it’s timing, but that’s wrong. Effects that would trigger on destruction or discarding will always resolve in a chain, and none of them will miss the timing, as long as the card that destroys or discards doesn’t have an additional part that still has to be resolved (see example above)
  • If you have a mandatory effect like Sangan’s (Effect: When this card is sent from the field to the Graveyard: Add 1 monster with 1500 or less ATK from your Deck to your hand.) and a non-mandatory effect like LPD’s effect, LPD will still be able to resolve it’s effect (in that case even more because the Chain would be different)
  • Example: You use Dark Hole again with LPD on your field and Sangan face-down on your opponent’s field.
  • Normally if both effects would be non-mandatory, you as the Turn Player would activate LPD’s effect as Chain Link 1 (like the example above)
  • Now in this case it’s different, as Sangan has a mandatory effect. If that’s the case the mandatory effect will always activate before the non-mandatory effects, therefore Sangan will be Chain Link 1 and your LPD will be Chain Link 2, regardless your Turn Player “Priority” (If both effects were mandatory, you would have to activate your mandatory effects first)
  • As we all know the Chain resolves backwards and because of that your LPD’s effect resolves first as Chain Link 2 was the last Chain part

Oh man I didn’t intended to make such a long Chain Resolving/Effect Timing part but well now it’s here … (I’ll probably copy that part and post it as a separate Rulings part too)

Mermail – Abysspike

This card will mostly trigger your discarding fodders effect while maintaining hand advantage by searching a LV 3 WATER monster from your deck (far better than his counterpart “Turge” in my opinion, who’s better during mid/late game). The important thing here is that you can ONLY search for monsters with EXACTLY LV 3 unlike “Turge” which can add a LV 3 or lower from grave, I’ve seen so many players who added LV 2 Water monsters with Pike, but that’s wrong! Read your effects dumbasses…

Mermail – Abyssturge

This is the counterpart I was talking about. Warning: those two do look similiar don’t mix them up 😀 (I did in my first duels too…)

As I said, this guy is only good during late game when your grave is already filled with plenty of targets, but it can really help at that time. So just 2 of them in my build, because i don’t really want to have them in my starting hand…

Abyss Soldier

He’s clearing the field of some troublesome monsters/backrow and activates your discarding fodders effect at the same time, so why not using him? Decent ATK and DEF, too.

Mermail – Megaloabyss


  • You can discard 2 other WATER monsters; Special Summon this card from your hand. When Special Summoned by this effect: Add 1 “Depth” Spell/Trap Card (except “Fish Depth Charge” or “Depth Amulet”) from your Deck to your hand. You can Tribute 1 face-up Attack Position WATER monster you control, except this card; this card can attack twice during each Battle Phase this turn.

Definitely one of your main bossmonsters and easy to summon through Abysslinde or his own effect. Regarding his own summoning: I still don’t know if the Atlanteans effects are activated when they are discarded for the summon of Megalo, personally I don’t think they activate as the discarding part is a Summoning condition and not an effect, but a judge, that one of my friends knows, said that Atlanteans effects do activate, so I’m not 100% sure, let’s just wait for Konami’s FAQ that will probably come in a few weeks.

You can only search for a “Depth” card if Megalo is Special Summoned through his own effect.

The other part that maybe causes troubles is the tribute effect: You can use the effect multiple times during your turn, but as I know, you can only attack twice even if you tributed two monsters in your turn, but I’m not 100% sure.

Moulinglace The Spiritual Ice-Inhabiting Lord


  • Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) by having exactly 5 WATER monsters in your Graveyard, and cannot be Special Summoned by other ways. When this card is Special Summoned: Discard 2 random cards from your opponent’s hand. The effect of “Moulinglace the Spiritual Ice-Inhabiting Lord” can only be activated once per turn. If this card leaves the field, skip the Battle Phase of your next turn.

Well I do use Moulinglace The Spiritual Ice-Inhabiting Lord (phew what a damn name lol), unlike Mike and Karlos, because I think he is just a broken card and is wonderful for OTK’s as you can still attack the same turn you summon him (a lot of people don’t realize that lol). The summoning part does look like Dark Armed Dragon or Archlord Krystia and now even the WATER part is released.

So why do I think it will help you OTK? First it has enormous Stats, then you can discard 2 cards from your opponents hand that will reduce the chance of your opponent getting a Gorz/Tragoedia/Fader on the field or activating Scarescrow. Too bad that it can only activate once per turn, I did have some crazy Frog combos in my mind 😀

In addition to that he can be easily searched out by Seahorsmen when needed and graveyard manipulation shouldn’t be that difficult with your discarding engine and Salvage.

To summarize: I do use DAD in DARK Decks and Krystia in Fairy Decks, why shouldn’t that apply for water decks too??

Deep Sea Diva

Nice tuner and can pull off some nice combos with Atlanteans, it’s definitely a must in my opinion if you use Atlanteans. I just don’t have the space for another Diva, but the card is really nice in Decks that use Sea Serpents. Summon Diva, Special Summon Armsman from your deck and normal summon another Sea Serpent from your hand to sync for whatever you like.

Atlantean Armsman


  • While this card is face-up on the field, once per turn during your Main Phase, you can Normal Summon 1 Level 4 or lower Sea Serpent-Type monster in addition to your Normal Summon or Set. (You can only gain this effect once per turn.) When this card is sent to the Graveyard to activate a WATER monster’s effect: Target 1 face-up card your opponent controls; destroy that target.

This guy combos well with Deep Sea Diva and you can discard him too to get rid of annoying continous cards/Field Spells or troublesome monsters.

Atlantean Marksman

I didn’t even use his special summoning effect once, except in a pure Atlantean Deck, but it is a good effect if you manage to inflict some battle damage 😀

What will happen more frequenty is discarding this guy for an effect, this guy can destroy a Set card of your opponent, that means either a Set monster or a Set backrow, nice to clean the field before performing an OTK.

Important to know: If the targeted card is chained to Marksman’s effect, you won’t get to destroy anything, as the targeted card isn’t Set anymore.

Atlantean Seahorsmen

Yea it’s Seahorsmen, I always thought it was Seahorsman lol. Well the translated name Sea Dragon Rider sounds better in my opinion, but Konami always has to make shitty names…

This guy searches your Megalo, Atlanteans and Moulinglace when discarded and has a decent ATK.

Effect Veiler

Why Effect Veiler? It’s just a staple in nowadays meta and will be if there’s nothing better to stop so many Meta decks nowadays like Inzektor, Dino Rabbit and stuff.

I do have one Depthscale Kraken that has a similiar effect as Veiler but Veiler is just more versatile and she can’t be countered easily as you could counter Depthscale.

In addition to that she’s my favourite card, so yeah in basically every deck I got 1-3 copies of her 😀

Mermail – Abysshilde

The reason why I don’t use Abysshilde is that I hate hand disadvantage and this is clearly a disadvantage as you will mostly use Hilde from your hand (or summon/set it from your hand) and then use your hand resources again to summon a Mermail through Hilde’s effect. I tried many builds with her and just found that she’s using up too much resources and isn’t really useful the whole time (the only good combo would be using her for Spiritual Water Art or sending her to grave with Genex Undine).

Mermail – Abysslang

I don’t really see the use for this card except maybe an attack lock, but that isn’t really the aim of a Mermail deck in my opinion. Therefore I don’t use him.


This card is just overpowered in late game, you can  almost get every discard fodder back, except Seahorsemen, and it generates so much advantage. Definitely a must in WATER decks, although I don’t want 3 copies cause early game you don’t really want to use it and normally you want some mermails or atlanteans in your grave. Nice to manipulate the grave for Moulinglace.

Mystical Space Typhoon

3 MST are appropriate in a swarming/ OTK deck, if you’re looking at the backrow of a Dino Rabbit, Inzektor, Hero deck there will always be a massive backrow, the only decks where 3 MST suck are Lightsworn, Chaos Dragon and Hieratics and some similiar swarming decks. So I like having 3 MST, but that’s just a personal preference, I guess.

Pot Of Avarice

This card’s broken in every deck that fills the grave quickly and mermails are one of those, sets up your grave for Moulinglace, too, if there were too many WATER monsters in your grave.

Depthscale – Kraken

A mix between Effect Veiler and a light version of Fiendish Chain fused with Doomcaliber Knight. Too bad that it only affects monster on the field and not everywhere. It’s searchable through Megalo and is really useful sometimes, even the ATK boost is useful sometimes.


This card is mainly there to summon Linde to the field and to trigger her effect either during the battle or through the Trap destruction effect, as her effect activates in grave and therefore isn’t affected from the negating condition anymore. Searchable through Megalo.

Spiritual Water Art – Aoi

This card is the light version of Trap Dustshoot for Water decks. Although you have to tribute a WATER monster for it, you still get to see your opponents whole hand and can discard a card from it is just broken.

This card combos really well if you have have a Depthsphere set, as you can special summon Linde with Sphere to protect yourself and get Aoi’s effect (This combo first turn is just broken).

Aegis Of The Ocean Dragon Lord

This card can save your ass for a turn if your opponent attempts an OTK or it can protect your Diva and stuf from a Torrential Tribute or a Dark Hole. I haven’t used it that much, but it’s a nice card in my opinion.

Maybe I’ll put something else instead of Aeagis in.

Sea Dragon Lord Gishilnodon

For the sake of WATER decks, not really useful since I built this deck but well I got one space left, so I put it in, maybe he will be kicked for a better card (Evigishki Merrowgeist) 😀

Btw he can combo really well with Lost Blue Breaker, Diva and Armsman (Summon Diva, Special Armsman, Normal Summon Lost Blue Breaker from hand, tribute Lost Blue to destroy a Spell/Trap, Gishilnodon ATK becomes 3000)

Gungnir, Dragon Of The Ice Barrier

Easily Summonable with Diva + Armsman + LV 3 Sea Serpent. Discarding and destroying is nice too, since all our discard fodder will activate with Gungnir’s effect.

Gachi Gachi Gantetsu

Can be summoned by Diva and saves you in a pinch or powers your monsters up, so that you can overrun your opponent.

Snowdust Giant

Nice effect and decent stats considering that your opponent will lose some attack, downside is that your opponent will know your monsters. But if you’re going to dump them anyways it’s not that big problem.

Bahamut Shark

Not that useful, as we still only have crappy Rank 3 or lower WATER Xyz monsters, which can’t attack or can’t attack directly with no Xyz Material.

Mermail – Gaioabyss

He is kinda good, but not really broken. I did summon him a few times but he wasn’t that useful.

Number 11: Big Eye

I’d rather summon him if the opponent has some big monsters, instead of Gaioabyss. No. 11 is just much more useful countering your opponents plays.

Additional Comment

Well that was everything I wanted to say and hopefully Mermails will get competitive in the future, but I don’t really wish them to become Meta. They definitely have the potential to do so although.

Comments, thoughts, ideas are appreciated. You can comment on WordPress or on my Facebook page, I’ll try to answer every question or comment.

    • That was the old decklist, look at the new one I linked on top. Look at the date it says August-02-2012, that was before the September banlist and the deck was really overpowered with Brionac 😉
