Rabbits

Seeing what we can do with the bunnies. This is a combo deck with some aggro potential given how easy it is to crack in with level 4s and 5s.
The main line is to get a board state where you have one level 5 and any other unsuspended digimon. Attack with the level 5, suspend for alliance, trigger the EX4 bunny rookie's inhereted to digivolve into BT12 Imperialdramon: Dragon Mode for 2. Suspend your opponent's threat, then check 2 at a minimum of 13k DP. After checks, trigger Dragon Mode's end of attack trigger to digivolve into BT12 Fighter Mode for free, bouncing the Dragon Mode to bottom your opponent's threat.
Bonus Points if:
1. Your champion in the pile is lighdramon to unsuspend the Dragon Mode as well
2. You also have enough memory to get in another attack with the Fighter Mode.
