Ruthless Greed

As an additional cost to cast this spell, exile half
your library, rounded up. If fewer than nine
creature cards were exiled this way, counter
Ruthless Greed. If Ruthless Greed is countered
this way, exile it.
Search your library for an artifact card and put it
onto the battlefield tapped, then shuffle. If an
Equipment is put onto battlefield this way, you
may attach it to a creature you control. That
creature phases out.
