As someone who finds themselves using cards in everything for their versatility and the interesting meta-control context that they provide, having each "card" have six faces was awesome to see realized. This is a great concept with an equally great thematic base set out for it. I can already see lots of enjoyment coming out of analyzing situations like these.
Just... solid, dude. For real. If I might ask, how are you randomizing the enemy encounters (systematically speaking, I'm interested in programmatic and theoretical structure :P)?
