The Legend of Kuruk [Avatar: The Last Airbender Prerelease Cards]

Whenever you cast a spell, create a 1/1 colorless Spirit creature token with "This token can't block or be blocked by non-Spirit creatures." Exhaust — Waterbend 20: Take an extra turn after this one. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1. Activate each exhaust ability only once.)
