WOAH epic Gains!
Yeah More Pain More Gain is definitely busted, might rework it to give flat Strength or a smaller multiplier.
Yeah the Hands-Free (Injure Arms) can end up with infini-draw, but any draw combined with a small deck and something like Feel the Burn (Injure for Stamina) or Pre-workout mix (Gain 3 Stamina) can end up with infini-draw.
Will either make it super rare so it's harder to pull off but fun when you do, or rework it somehow. Thanks for playing!
