Golgoroth, the Unbound

When ever a creature dies put a +1/+1 and light counter on Gologoroth, the Unbound.
When Gologoroth, the Unbound reaches 12 light counters remove them and destroy all creatures you dont control.
"Crota rose to petition / Father, cut the shapes into a tablet / Give me the tablet / I will bear it in battle / And tithe one side of my sword to you / Oryx cut the shapes into a tablet / But he guarded the shapes / He set the tablet in Golgoroth/ Where the new flesh grew as Eir decreed it."-Books of Sorrow
