Really neat concept! It was a bit confusing at first, but once I got how to play, it was a lot of fun thinking through how to build each hand, which new cards to take, the probability of being able to sabotage the enemy (or accidentally sabotaging myself)...
If this were to be expanded, I'd like to have more feedback for dealing the final blow, because the transition to choosing new cards is kind of abrupt. But that's a super minor nit. This is great!
