Zirilan, Hellkite Warlord

{1}{r}{r}, {t}: Search your library for a Dragon
creature card and put it onto the battlefield.
Then shuffle your library. That Dragon gains
haste. Sacrifice it at the beginning of the next
end step.
Whenever a creature you control attacks, it gets
+1/+0 until end of turn for each Dragon
creature card in your graveyard.
