Koll's Forge

Enchanted and equipped creatures you control
have indestructible while attacking.
Whenever a nontoken aura or equipment you
own is put into your graveyard from anywhere,
you may put a token copy of that card onto the
battlefield with "Sacrifice this aura or equipment
at the beginning of your next end step."
{1}{r}{w}, {t}, Put a +1/+1 counter on each
enchanted or equipped creature you control.
