Soul of Alara

Eminence — As long as Soul of Alara is in the
command zone or on the battlefield, the first Elemental or Incarnaton spell you cast each turn
has "Evoke—Exile a card that shares a color with
this card from your hand, then draw a card."
Ward {x}, where {x} is half the number of nonland permanents you own in exile, rounded down.
Elementals and Incarnations you control cannot
be sacrificed.
