Jin Dahaad, Frozen Peak Wyvern

Whenever Jin Dahaad, Frozen Peak Wyvern deals combat damage to a creature, tap that creature and put a Frostblight counter on it. Creatures with Frostblight counters don't untap during their controller's untap step. Frostblight counters cannot be removed. When Jin Dahaad leaves the battlefield, remove all Frostblight counters from all permanents.

Sacrifice a non-creature permanent: Jin Dahaad gains hexproof until end of turn.
