A very cool game idea! It's not too big but pretty fun to play for a bit.
I don't know if you're planning to patch this in some way, but in case you are, there are some bug reports:
1)Oracle's passive heals the opponent if Oracle's ability trashes the opponent's deck. Doesn't seem like the intended behaviour and also turns off an alternative build.
2) Shock doesn't seem to work. I applied it to the enemy Carnival Carry on round 1, but they still pulled their entire combination of cards after copying Adrenaline.
