Gambit: (Solo) Take No Damage And Stun The Villain While Bui

The title pretty much says it all. Play cards that enable you to take no damage while providing you with a tangible benefit, and, stun the villain as needed. Do this until you have a massive pile of charge counters in front of you, then unload and kill the villain in a couple of turns. This deck is definitely a slow burn but it's pretty effective, and quite satisfying at the end.
