Predict Future

Opponents play with the top card of their
libraries revealed. Once during your turn you
may reveal a card in your hand. If it matches a
card type with the top card of any opponents'
library that opponent reveals their hand to you
only. Then exile a random card from that
opponent's hand. You may cast it from exile
during your next turn. Spend mana as if it were
any color while casting it.
