Azir, the Emperor of the Sands

When you cast this spell, exile all cards from all graveyards, then create that many 2/2 white
Sand Soldier creature tokens.
Azir's power and toughness are each equal to the number of creature tokens you control.
Ultimate — {w}{w}, {t}: Other creatures you
control get +1/+0 and gain vigilance and first
strike until your next turn.
