Treasure Hunt

"Each creature with Treasure Hunt has a list of things it's looking for. While a treasure hunter is in play, it checks every card you draw on your turn to see if it's on the list. Once you've drawn all of those cards, you receive the listed effect. The cards do not need to be drawn in the same turn. The effect only happens once."
