Godrick the Grafted

Godrick the Grafted enters the battlefield with
X +1/+1 counters on it, were X is the amount of Demigods you control.
When Godrick the Grafted dies, exile it, search
your library for Godrick's Great Rune and put it
into your hand.
"I command thee, kneel!
I am the lord of all that is golden!"
