Void Sovereign

Eminence—As long as Void Sovereign is in the command zone or on the battlefield you may pay

Immutable—This spell can't be countered, has protection from everything, is immune to cost reduction effects and may only be cast from the command zone

Flying, Vigilance, Deathtouch, Provoke

Void Sovereigns power and toughness are both equal to the number of cards in exile.
