Test deck im using for Alphamon BT13. May replace all bt9 alphamon with bt13 alphamon. May also add kongou over 12 lvl 3s and 10 lvl 4s (take out 1 bt13 dorugamon and 1 ryudamon) and add in kongou and 1 more option card like metal cannon.
Kongou + BT13 alphamon is basically a turn shutdown for your opponent as the only digimon that can attack are playcost 8-9 which gets around most lvl 6s and lower and prevents attacks by blast ace Garuru and Grey. Deck feels a little slow for the format but is still solid. Biggest issue is finding the right time to use options since they are so limited.
