Golem

Damage dealt to Golem is dealt in the form of
-1/-1 counters.
At the beginning of your upkeep, if Golem has 6
or more -1/-1 counters on it, you may create a
3/5 red Golem Head creature token with indestructible and flying. When Golem dies, sacrifice this token. You may only have one
Golem Head on the battlefield at any time.
