Good for Mindgate (Yay trios!)
I can definitely see this being used, especially in entropy. I think it was a good choice to make that the element for the ability, because of its healing cards. It could possibly hurt decks that rely on key cards, or it could help them. (Suddenly the opponent draws Black Holes for the next 3 turns xD). And while I can see it being used, it seems just to be a niche card. I wouldn't mind it costing 4 to play.
