Flameskull

“Flying <br>Flameskull can't block. <br><em>Rejuvenation</em> — When Flameskull dies, exile it. If you do, exile the top card of your library. Until the end of your next turn, you may play one of those cards. <em>(If you cast Flameskull this way, you can't play the other card, and vice versa.)</em>”
