I was looking for an unconventional X-Antibody deck. When at exactly three or four security (and you have three+ memory left), you can pull off this combo:
Attack with angewomon. Digivolve for 3 into ex1 magnadramon. Trash the top security card to unsuspend and attack again. At this point you'll have gained another memory from bibimon. Then recover a security card. If you have kari out, you'll also gain a memory. During this attack, use the x-antibody attacking effect to digivolve for 1. This will clear any 3k or smaller digimon from your opponent's board. After the attack finishes, the End of Attack trigger will let you take the top card of your security to unsuspend. Then attack again. That's three one-check attacks off of a level 5 with three memory up in mono-yellow. You can surprise combo-kill any opponents with two or fewer security left that way.
