Sarkhan, Dragon Ascendant

When Sarkhan enters, you may behold a
Dragon. If you do, create a Treasure token.
(To behold a Dragon, choose a Dragon you
control or reveal a Dragon card from your hand.)

Whenever a Dragon you control enters, put a
+1/+1 counter on Sarkhan. Until end of turn,
Sarkhan becomes a Dragon in addition to its
other creature types and gains flying.
