Water Combo

Needlefibre turbo deck, with 6 1 card Needlefibres, a ton of combos to go into Needlefibre, and some hand loop stuff built into the combo.

I wanted to take advantage of the space in the deck to run 9 hand traps. 9 helps really ensure that we'll see a hand trap most of the time, and there just weren't other cards I considered essential enough. Nibiru is really good right now with all the combo running around, and Imperm and Crow are also really good against Eldlich and Adamancipator going first or second, so this split seems good. I'm not maining Dark Ruler, because IMO it's not good enough against Eldlich Synchron or against any deck with space for Jet Synchron combos/literally any 1 card Needlefibre. They're in the side deck for when a hand trap isn't as good or better.

We have 3 Deep Sea Diva and 3 Neptabyss with 3 Dragoons, 3 Minstrel, Lappis, and Moulinglacia. This means Diva ends on Moulinglacia + VFD having drawn 2 cards and hand looped our opponent for 3, with Neptabyss also making VFD + Draw 2. I cut the Formula Synchron combo to make space for some backup/followup plays in Bujinki Ahashima, Apollousa, and Bahamut Shark into Toad (running 3 cards just to draw a single card seemed excessive). 3 Heavy Infantry makes sense, since we go into Coral Drgon and Crocodragon as part of our main combo, and the potential to seriously break boards while comboing off is super clutch.

1 001 and 2 O-Lion are pretty key. 2 O-Lion is about always having an O-Lion to combo off with even if you brick, since the whole deck is pretty dedicated to comboing off one route.

3 Deep Sea Aria help find us any low-level sea Serpent, usually Diva, to start combos. The deck doesn't excel at putting monsters in the GY, but this card gives you 3 more situational copies of Diva, which is clutch. Pot of Avarice is at 3 which is insane, and I genuinely think more decks can play it. It contributes greatly to the grind game while also giving card advantage. While it might seem like a bit of a "win more" card, the truth is any deck that can easily put 5-10 monsters in the GY off of 1-2 cards should probably be running this. The card also isn't once per turn, which decks like this can take sometimes take advantage of (though not as well as Salamangreats, just sayin'). One for One is an extra Neptabyss, which is full combo, as is Abyssteus + Dragoons, which is what I like to call "overcombo".
