Unliving Drake

When Unliving Drake is put into the graveyard,
exile it with one time counter. During your
upkeep, remove a time counter from Unliving
Drake. When Unliving Drake has no more time counters on it, cast it without paying its mana
cost. Put a number of +1/+1 counters on
Unliving Drake equal to the number of times it
has been exiled and returned to the battlefield.
