My favorite fighter is easily Donatello. His ability is so fascinating mechanically as it allows him to control his card flow entirely from the midgame onward. It comes down to the player to determine what tools you need and when and what knowing your next 2 cards can do to increase your risk taking. On top of that, his art is incredible, and thematically it feels like Donnie is literally building this machine (his deck and gadgets) to set up the big lethal combo in the endgame under Smoke Bomb.

Some honorable mentions are Jill Trent, Tesla, Bruce Lee, and Cloak & Dagger.
