Cheese turn 2 wins by abusing red greymon, metalgrey x, and zeigreymon. Go into metalgrey using red greymon (blue greymon works if the opponent has 2 digimon) and jamming mailbird, go into metalgrey x and swing 3 checks (if you use blue greymon and opponent has 2 digimon, swing metalgrey first and unsuspend then go into metalgrey x to swing 2 so still 3 checks) then digivolve into zeiggreymon to take out the final 2 security, and attack with a promoted rookie to end the game.

Cheese turn 2 wins by abusing red greymon, metalgrey x, and zeigreymon.

You need 6 memory if the opponent doesn't have 2 digimon, and you need 4 if they do. Blazing memory boost and your tamers can provide the memory to enable this on turn 2. Even if you can't pull it off, you can put significant pressure on the opponent very quickly and threaten a turn 3 win. And metalgreymon deals with blockers, if you really need to deal with a big blocker after your first big turn you can use the old mailbird to digicross if they have 2 digimon and stun it when you swing so you can get past it.

Final note: if they ever make another blue flare metalgreymon that can use non blue greymons, cut wisteria memory boost and a bt19 gaossmon, and play a fourth red greymon, 4 of that blue flare metalgreymon, and 4 og mailbirdramon. At that point, the deck would be perfectly consistent.
