Pluto, Dwarf Overlord

Outer Planet—When Pluto enters the battlefield, planets in your graveyard may be cast as if they were in your hand.

Elliptical Orbit—Pluto, Dwarf Overlord, may target X creatures, where X is equal to the cost paid during it's initial summoning. X target creatures have a stun counter placed on them. (During a creature's untap step, instead of untapping, remove a stun counter.)
