Slumbering Ravager

Slumbering Ravager enters the battlefield with
eight slumber counters on it.
As long as Slumbering Ravager has a slumber
counter on it, it's a forest land (it's not a creature.)
Whenever a creature attacks you, remove a
number of slumber counters from Slumbering
Ravager equal to the creature's power.
