Hextia, Elder Entity

When you cast a spell that deals damage to exactly
one target, copy that spell for each other target the
spell could target. Each copy targets a different one
of those targets.

If Hextia, Elder Entity dies or is put into exile from
the battlefield, return it to the battlefield at the
beginning of your next upkeep.

{p/u}{p/b}{p/r},{t}: Instants and sorceries in graveyards gain flashback until end of turn. The flashback cost is equal to its mana cost.
