In the game that I'm creating (no name for it yet...) I've decided to debuff @Ravage's card. Instead of making his special ability have a 2-turn cooldown, I've decided to give him 0 ATK. I did this because some cards will have an ability to deal additional damage so he can use that to attack his enemies. For instance, I've been thinking of @DragonFireGames's card and I think the special ability would be dealing an additional 5000 ATK for one turn with a 2-turn cooldown.
