Notes & Combos

Crystron K9 is a lot of fun i already played it in tcg (without noroi tho) and now in md. It has it weakness going second but having access k9 engine and crystron can break boards more than enough. Going first i try to make the cringe board with spell cancellor if possible. Just because i can.
