Dark Deal

Dark deal is a versatile spell that can either be used to deal with low health enemy units or to empower your own units. The amount of rage that you generate for 0 ember is incredibly impressive, making it fit incredibly well into decks that benefit greatly from rage. This card is very good at turning tanks into bruisers (high damage and high health combined), and the health lost is usually negligible for a tank.

It should obviously never be used on an enemy that will not die by the end of the turn, as it provides it with far too much damage. Never make the mistake of using this to damage a boss.
