Generally speaking, fusion deck is not competitive in PVP because of the heavy resources. 1 fusion monster = at least 3 cards (2 materials 1 poly), not to mention the high chance of bricking. Even if managed to get it out, 1 S/T is enough to 🔥 it
Lol Super Poly only help e-heroes a little, but never make them winning. It was actually make Shaddolls winning. Tbh Konami should've released an actually decent HERO like Omni HERO or the lvl 6 Masked HERO(lvl 8 still too broken for DL) alongside their good supports like Emergency Call. Otherwise HERO will always be tier crap
