Captain Gangplank

Whenever a Pirate you control attacks, create a colorless Powder Keg artifact token with "{1}, Sacrifice this artifact: Deal 1 damage to target creature."
{3}, Sacrifice up to three Powder Kegs: Captain
Gangplank deals X damage to all creatures you
don't control, where X is the number of Powder
Keg sacrified this way.
"Everyone pays!"
