Wait bro, if you want to build this deck, you have to have enough kids in the Extra Deck, because they are quite important, so important that without them you don't have a boss to play. Anyway, at least

Instructions for Playing Mermail Atlantean
Sections covered in this guide:
Skill
CORE
That's right Peter, this one is level 4
Both of them, when sent to the grave to activate the WATER monster effect, will trigger the bombardment effect (even if detacted by Xyz monsters like Abyss Dweller).
Like that guy but throws up to 2 WATER to jump and has the ability to tribute monsters to punch once to OTK
Extra Deck
This monster simply means that it cannot be destroyed by combat. If it hits enough, activate the effect to double the ATK and DEF of a Rank 4 monster or lower to OTK, usually increasing it for Number 37 because its body is big and powerful. ability to reduce the ATK of enemy monsters
big body, with Abyss Dweller, it increases ATK to 3100, but also reduces the ATK of all opp monsters by 1000, easy to upgrade
You don't know what to do with mermail's body link 1? Don't worry, me too
If you ask 4 stars + how many stars get this one, my answer is 7 + 2
Well, if you want to get to Trishula, you have to 4 + 3 + 2. This guy asks for 2 or more non-Tuner, in return you get 1 card in your opp hand, 1 on the field and 1 in the grave NO TARGET
Staple
These guys are so picky
level 4 self-jump (if drawn and in empty hand, it will brick or cost 1 normal summon), has good negate bait ability, if opp does not negate this effect, you can banish 1 of opp's face-up cards until the next standby phase According to you, create conditions for OTK or staging
Actually, they're a bit of a flop at the moment
Combo

I> normal deep sea diva, jumps Heavy Infantry from Deck, links to Anemone, Anemone jumps back to Infantry from grave
