This is my attempt to create a consistent pure Mecha Phantom Beast. I've tried throwing in the Dragon Rulers but haven't liked it that much. Thus far, the deck has been pretty fun but I'm looking to make it more competitive. I can xyz into powerful monsters easily with it if I open with a Hamstrat/Stealthray and Megaraptor/Harriard. I had Warburan at 3 initially but in testing it started to seem like a dead draw. Most of the spells are meant for trading a token for a strong monster and can really help make my side of the field stacked.
Yeah, b/c only being able to live in a single deck, requiring 4 specific monsters of different names in the Grave, and being a physical card in your hand that can be dead rather than a tutorable monster in your Extra Deck aren't forms of being balanced.
