“Griffin Card” by uheartbeast.
“[Y]ou play different number cards to give your pet [g]riffin the power it needs to defeat the evil growing tree creature.”
Besides the lovely pixel art, I enjoyed “Griffin Card” because of its focus on the core mechanic: Balancing your enemies’ defense and your griffin’s attack with the help of the number cards. And there are also many good (and bad) tree-related puns. >>PLAY
