Grand Essence Orb

Flash
Sleight of Hand - You may exile an Instant or Sorcery from your hand while an opponent has an Instant or Sorcery on the stack rather than pay Grand Essence Orb's mana cost, otherwise exile Grand Essence Orb at the beginning of your next end step.
Instants and Sorceries cost {2} less to cast.
Too valuable to share. Too difficult not to.
