The God's Blacksmith

Whenever one or more creatures you control
attack, you may pay X then look at the top X
cards of your library. Put an Equipment or Aura
from among them onto the battlefield attached to
a creature you control. Put the remaining cards
on the bottom of your library in a random order.
{w}{u}{g}, {t}: Create a token that's a copy of target Equipment or Aura you control, then attach the
copy to a target it could legally attach to.
