Bargaining Demon

Haste, Double Strike, Deathtouch
Bargaining Demon cannot block.
When Bargaining Demon is blocked by a creature, you may have Bargaining Demon lose Haste. If you do, regenerate Bargaining Demon, and remove it from combat, and the creature that blocked Bargaining Demon gains Haste. The same is true for Double Strike and Deathtouch.
