Desperate Piracy

Pirates you control cost {1}{b}{r} less to cast
this turn. (For example if a pirate costed {2}{r}, it would only cost {1}.)
At the beginning of your end step, if this
card was put into the graveyard this turn, plunder 1 for each pirate spell you cast this
turn. (Discard a card, if you do, draw a card.)
