Crashing Wave - 47 - (Avatar: The Last Airbender)

As an additional cost to cast this spell, waterbend X. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1.)
Tap up to X target creatures, then distribute three stun counters among tapped creatures your opponents control. (If a permanent with a stun counter would become untapped, remove one from it instead.)
