Yu-Gi-Oh/Mermail Deck Build


Hi Exo,

I am wondering if you could give a build on a Mermail Deck that would be competitive for the new format.  I have played the deck with and without the Genex Undine/Genex Controller and have had success with both.  With the banning of Tidal and Lavalval Chain, I was hoping you can help with a build that can still be competitive without them.


With Dragoons back at 2 copies per deck I'm not sure whether I want Genex Undine or not. Without Tidal to drop it seems rather underwhelming, and Genex Controller doesn't make summoning Trishula as easy as Deep Sea Diva does.

I think I'd stick with the Pure Mermail variant until Neptuabyss is released. I'd probably start with something like this:

3 Mermail Abysslinde
3 Mermail Abysspike
3 Mermail Abyssteus
3 Mermail Abyssgunde
3 Atlantean Marksman
2 Mermail Abyssmegalo
2 Atlantean Dragoons
1 Mermail Abyssleed
1 Mermail Abyssturge
1 Mermail Abyssocea
1 Atlantean Heavy Infantry
1 Deep Sea Diva
1 Moulinglacia the Elemental Lord
1 Aqua Spirit

3 Upstart Goblin
3 Mystical Space Typhoon
1 Soul Charge
1 Raigeki

3 Abysss-Sphere
2 Breakthrough Skill
1 Torrential Tribute

1 Mermail Abyssgaios
1 Number 11 - Big Eye
1 Mecha-Phantom Beast Dracossack
1 Bahamut Shark
1 Castel the Skyblaster Musketeer
1 Evilswarm Exciton Knight
1 Daigusto Emeral
1 Abyss Dweller
1 Leviair the Sea Dragon
1 Mechquipped Angineer
1 Mermail Abysstrite
1 Armory Arm
1 Armades, Keeper of Boundaries
1 Dewloren, Tiger King of the Ice Barrier
1 Trishula, Dragon of the Ice Barrier

Give that a go, see what you think.

I'm able to answer any and all questions related to the English Yu-Gi-Oh! game itself. This includes, but isn't limited to:

Deck Fixes: Either making suggestions and improvements on a deck you've already built, or building a deck from scratch for you. In either case, please give an idea of the kind of deck you're building, the level of play you're planning to use it in (small tournaments, regionals etc), and the kind of budget you're on.
Please format decks in a way that's easy to read. Each card name should be on its own line, with a number before it indicating how many you're playing. Please split decks into Monsters, Spells and Traps.

NOTE: A level of reasonability is assumed with this. I cannot build you a nationals winning deck based on monsters whose name starts with the Letter 'A' on a budget of 4($6)... Nor will I generally respond well to Questions touting "No Xyz, Synchro... etc" or disallowing cards from certain parts of the show. I haven't seen the show in a number of years and find these conditions to usually be poorly-defined.

Rulings: On any card interacting with any other card(s). Tell me the scenario, and I'll tell you what happens.

I won't be answering questions on whether a trade is fair or not, or on how much X-card is worth, as both these kinds of question can be answered by using Ebay's completed listings page.
