This deck is so silly because on one hand it kinda builds itself, just fill the deck with big assholes and slam them down, but it also has such a variety of choices for deckbuilding from the old Demon Lords, the supplemental mill and draw engines, the tamers and options you can play, and all sorts of silly techs that are possible.
Ive been using tarnished hero instead of porky. 3 cost keeps turn most of the time so you can still drop a body on the turn you out the floodgate. And either a discard or memory later on doen the line is good too
I don't think Leviamon ex6 is that important into numemon for the fact that pretty much always the opponent is going to have more bodies than you on the field. It's true that it is indeed strong, but the removal being conditional in a deck that doesn't have the capabilities to keep a board is really important in valuating the card. Shoto is going to help this deck so much in ex7, it always feels bad to have only creepy and sleep to avoid an opponent check right now, and giving lucemon chaos mode blocker is so good
