Notes & Combos
This is the best Turn 2 deck in the game. Searching a Kaiju is great against monsters like Nightingale and so on.
For turn 1, I recommend summoning Linkuriboh with Byblisp. It resummons from the Grave if your opponent's monster has a Preda counter from your Skill. then summon Hydra to link climb into phoenix (with a possible draw 1) and unicorn to deal with backrow
My endboard was mostly Linkuriboh + Dragostapelia (and another monster) + Super Poly and Backrow.
Ultra Poly and Mudragon didn't do to well imo. there replacable. For your extra deck I think Dragonecro is a more viable option with all the shiranuis on the ladder.
