Tatter Sanity

Incantation 1 - {b}{b} (You may pay {b}{b} and exile
one card from your hand rather than pay this spells
mana cost. If you do, it cant be countered.)
Target player discards two cards. If you paid this
spells incantation cost, instead that player reveals
their hand. You may choose two nonland cards
revealed this way. That player discards those
cards.
