Rosemon (X Antibody)

This is the list of one of my local decks I use to play, I can win and face strong decks like Leviamon X or Numemon without any problem.

Your gameplan is easy, suspend and stun the opponent's board while you keep spamming rosemon lines using just a little memory (you reduce digievolution cost with your sources and you get a lot of memory with your tamers)

A few notes:

combine Palmon Bt14 with Palmon X antibody to get +2 memory easily

sometimes you will digievolve rosemon burst mode without doing burst digievolve, it cost 5 memory, but with your tamers and your sources, will cost between 2 or 0 memory

combining tamers and sources that reduce digievolution cost will get you from palmon (bt14 ideally) to rosemon with very very little memory meanwhile you basicly suspend all your opponent's digimon. combine this with rosemon burst mode to stun even futher (every opponent digimon suspended and tamer don't unsuspend the next turn) and attack the enemy security. If your opponent swarms the fiel, for example, playing digipolice, you can easily suspend all their digimons and trash for 2 or 3 security with rosemon BM (combining with lillymon ex1 and lilamon sources, you can check 2+3 trash, destroying the enemy security, while checking with a High dp digimon).

Finally, Use rosemon X antibody as your main tool to stun the enemy board on the oponent turn, suspending on play digimons and when a digimon moves from breeding area is a really strong way to stun opponent digimon.
