One's Mistake

Investigate {2} (If investigated then target
opponent chooses three cards, and exiles the two
you didn't pick.)
If target opponent has less than 5 cards they draw
up to 5. They then give you their hand, you are
not allowed to see the cards. Shuffle the cards,
then target opponent chooses two. Reveal those
two cards and choose one, target opponent exiles
the other. The card you chose goes into your
hand.
