Waterbender Ascension (TLA-079) [Avatar: The Last Airbender]

Whenever a creature you control deals combat damage to a player, put a quest counter on this enchantment. Then if it has four or more quest counters on it, draw a card.

Waterbend 4: Target creature can't be blocked this turn. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1.)
