Deckhand Klabautermann

Other Pirates and Goblins you control get +1/+1.
Whenever you attack with one or more Pirates or Goblins, flip a coin. If heads, exile the top card of
your library. You may cast that spell until the
endstep of your next turn. If tails, create a 2/2
black Pirate creature token with Menace that is
tapped and attacking.
