Reverse Card pack is very, very awkward with snap, since snapping two reverse cards just means your next two actions are reversed, and unless you've got a Wrong Sword and a Wrong Axe next up, that's only going to screw you over. I'd recommend giving it a big rework in general - most other packs have benefits aside from just their inflict-status-do-damage synergy, and reverse card. (Yes, you can reverse a reverse card, but that requires using both reverse cards (without snapping) and then not being able to use Wrong Sword except to damage yourself. And inflicting the enemy with Reverse usually only does 6 damage at best.)
