Gregor, the Playmaker

Multikicker {w/u}
When Gregor, the Playmaker enters the
battlefield, exile up to X target instant cards
from your graveyard, where X is the number
of times Gregor was kicked. Put a kick counter
on each of them.
When Gregor attacks, copy each exiled card
you own with a kick counter on it. You may
cast the copies.
