Satan's Foothold
[Rainbow EE | TC | -/- | Ephesians 4:26-27]
Place in your territory: Your evil enhancements on opponents' heroes that decrease strength and/or toughness decrease by double the printed amount on the enhancement. Poisons and diseases are protected from healing. Cannot be negated.
I've always thought the poison/disease/decrease defense was a fun idea, but it just doesn't seem to have much support, so that was the idea behind this card.
