Varadast, the Undying Mage

If Varadast would take damage or die, you may
remove a counter from it instead.
{1}{r}, {t}: Reveal the top three cards of your
library, then exile a card from among them and
put the rest onto the bottom of your library in
any order. You may play the exiled card as
though it had flash. Otherwise, put a
+1/+1 counter on Varadast.
