Hircine, Prince of the Hunt

Indestructible
Hircine, Prince of the Hunt can't attack or block
unless your devotion to red and green is seven

Whenever a creature enters the battlefield under
your control, it fights target creature. If a
creature is destroyed this way, Hircine deals 2
damage to that creature's controller.
