It says:"Action: Target opponent discards a card from his hand. Then, draw a card."

Question 1: Who choose which card to discard?

1)target opponent

2)random

Question 2: Who draw a card?

1)target opponent

2)you

Just based strictly on the wording, I would say the opponent chooses which to discard and you draw the card.

Yeah, he definitely chooses a card to discard, then you draw a card.
