Gornog, the Red Reaper

Rulings

Gornog's third ability doesn't have a duration. It will remain in effect until the game ends, the target creature leaves the battlefield, or some subsequent effect changes the creature's characteristics, whichever comes first. — Gornog's third ability overwrites the target's existing creature types. Once the ability resolves, that creature will be a Coward and won't have its previous creature types. It retains any other types and supertypes it has as well as any subtypes that aren't creature types. — Once a creature has blocked a Warrior, turning that creature into a Coward won't remove it from combat or cause the Warrior to become unblocked. (The Coward might suddenly have some regrets, though.) — The bonus granted by Gornog's last ability changes as the number of Cowards your opponents control changes.
