Photon Unleashed

Haste, Unblockable, Indestructible
Sleepy X. X can't be 0. (When this creature enters
the battlefield, pay X life and put X sleepy counters on Photon Unleashed. At each end step, remove a sleepy counter from Photon Unleashed. If you can't, sacrifice
it or exile it, then return it to the battlefield under your control.)
