Sheamus O'Leary the Carefree

When this card would leave the battlefield, you may exile it. If you do, return it to the battlefield under your control at the beginning of the next end step and each opponent may draw a card. For each opponent who does, you gain a luck counter
At the beginning of your draw step, you may pay any number of luck counters, look at that many cards from the top of your library. Choose one and put it into your hand. Then put the rest on the bottom of your library in any order.
