I'm going to start running a daily discussion around cards, relics, enemies etc. just as they do on the subreddit. I figured the format is good so we can just copy it and tweak if needed. Let me know if you'd like something else from these discussions

Demon Form (Power)

Energy Cost: 3

At the end of your turn, gain 2 (Upgraded: 3) Strength

(Strength: Buff. Increases attack damage by 1 for each point of Strength.)
