The Big Scam

As an additional cost to cast this spell, discard a nonland card, sacrifice a creature, and sacrifice a
non-creature permanent.
Each opponent reveals their hand, you may exile
a card from among the revealed cards with equal
or greater mana value than the discarded card.
Then, for each permanent sacrificed to cast this
spell, gain control of target permanent an
opponent controls with equal or greater mana
value that shares a card type with the sacrificed permanent.
