What a cool idea for a thread! I'll do two teams - one with player stats weighted heavier (and a full team, not just 9), the other with card significance (sticking to the OP 9-card rule). My position players are in batting-order form for the stat significance. The pitchers are in no particular order. I'm an Indians fan, so I'll use American League rules and add a DH.
