Dude. This is absolutely excellent. I think the mechanics are all incredibly interesting and that you could expand so much on this idea. I think the balance is really well done, I didn't mind the enemies coming from random spots because that gave "Speed" more value as an asset. I would have preferred if the minions had a health bar instead of wasting a card to get a health bar. There is so much potential to add more enemies, more heroes, enemy and hero weaknesses (druid strong against bats and wasps, weak against zombies, necromancer strong against zombies and vampires), the pacing was neat, this has replay value and kept me engaged. Solid work!
