The Winged Dragon of Ra

Shroud, Flying
If The Winged Dragon of Ra would be exiled,
shuffle it into its owner's deck instead.
The Winged Dragon of Ra's power equals the
combined power of the creatures sacrificed to pay
for its transform cost. The same is true of its
toughness.
Pay life until you have only one life remaining:
Add that many +1/+1 counters to the Winged
Dragon of Ra.
Pay 2 life: destroy target creature.
