Concussive Mind Blast

Target player reveals their hand to you. You
choose a nonland, noncreature card from it.
That player discards that card. You may play
the discarded card until the end of that player's
next turn, and you may spend mana as though
it were mana of any color to play that card.
Buyback — Discard two cards.
