Thought Swap

You and target opponent reveal their hands.
Exile a card from that opponents hand, you may
play that card for as long as it remains exiled and
spend mana as though it were mana of any color
to play that card. Then that opponent exiles a
card from your hand. They may play that card
for as long as it remains in exile and spend mana
as though it were mana of any color to play that
card. Then draw two card.
I'll show you mine if you show me yours.
