Xeridia, Mother of Tarzzapum

Devourer’s Paradox: When Xeridia, Mother
of Tarzzapum enters the battlefield, choose a number from 1 to 3. Exile that many cards at random from each opponent's hand. As long
as those cards remain exiled, you may cast
them using mana of any color. If you cast a
spell this way, copy that spell. You may choose
new targets for the copy.
