Ah, the Hungry Creature! Bane of riddlers everywhere, always lurking, waiting to gobble all the cards in your hand... or an unlucky hero.
Anyhow, can I discard an encounter card that's in my hand, such as "Lost in the Wild", as a 0-cost card? Lost in the Wild says it cannot be discarded by player card effects, but Hungry Creature is not a player card.
