Aside from the main mechanic, which was interesting, I also thought it was neat how you could influence your deck building by choosing enemies that might have the cards you want. I ended up making a build that stalls with 3 defense cards into a body slam last hit, but was disappointed to find my defense caps at 9, hah.
I'm curious if you have ideas about what sort of mechanics a theoretical full version of this game would have. It seems to me that overcoming the pretty obvious dominant strategy would be difficult.
I really enjoyed this, though, good job!
