Cold Light

When Cold Light enters the battlefield, exile
target non-Basic permanent and all permanents
with the same name for as long as it remains.
As long as Cold Light is on the battlefield, if your
opponents would cast or play cards with the same
name as cards exiled by Cold Light, exile them for
as long as Cold Light remains on the battlefield.
The void of eternity pulls all versions of oneself out of
the timeline and into it's frigid, blank grasp.
