So apparently Ukkomon can make this a better midrange/rush deck in BT-15, so let's see if we can make that magic happen for BT-14, before the X-Antibody cards arrive. I'm also trying to make the armor purge bear and BlackKingNumemon work before they most likely get replaced with the generically better bears.
Don't rush with your Ukkomon or floodgate rookies early on, let them sit and be annoying and generate more bodies and memory, and card draw from the Tsunomon as you evolve. You'll mostly be hard playing your Numemon, though you might see a reason to have the one cost evolve Numemon evolve on an Agumon once in a while. Use Geremon to get RB-1 Numemon, BlackKingNumemon, and PlatinumNumemon in the trash for your Monzaemon to absorb on play. Cooties Kick to get past blockers and steal memory, Kongou to help against yellow and swarmy boards, Satsuki is good for helping your rush strat and will make her opponent respect her and her slime children. The BT-14 Numemon is great at getting her out and the rush ain't too shabby. I wouldn't leave her under anything but the Monzaemon though. Most everything else is too fragile. Ruin Mode because sometimes you gotta wipe a board, and you have a couple of silly ways of getting PlatinumNumemon out to use him.
Try to win fast. Play kinda like rookie rush but with some top end stuff to help you keep a board.
