Vito, Mind Infiltrator

Whenever Vito, Mind Infiltrator deals combat
damage to an opponent, that opponent exiles a
card from their hand at random. You may look
at and play that card for as long as it remains
exiled, and you may spend mana as though it
were mana of any type to cast it.
Whenever you play a card that you do not own,
each opponent loses 1 life, and you gain 1 life.
