Hellbent

(Note that this is still somewhat speculative, as Dissension has not yet been released.)

Hellbent is the Ability Word of the Cult of Rakdos, the Black-Red guild in Dissension. Permanents and spells with Hellbent become better if you have no cards in your hand, for example a creature might get power and toughness bonuses, or a spell might deal more damage.
