Walk the Plank

Gain control of target creature without flying
and with power X or less, then sacrifice it. You may put a +1/+1 counter on target Fish, Kraken
or Merfolk creature. If you control a Pirate, create a colorless Treasure artifact token with
"{t}, Sacrifice this artifact: Add one mana of any color to your mana pool."
