Lord Julius of the Mist

{u}{g}{t}: Copy target spell, activated, or triggered
ability. Lord Julius of the Mist phases out.
(While it's phased out, it's treated as though it
doesn't exist. It phases in before you untap during
your next untap step.)
Partner with Lord Isana of the Veil (When this
creature enters the battlefield, target player may put
Lord Isana of the Veil into their hand from their
library, then shuffle.)
