Hello to everyone,
just to confirm, when I play "Bladewind":

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

Is the opponent that chooses the card to discard ? Or I'm me that discard a card to him at random?

He chooses, since the card doesn't say he has to discard a random card (like for example the description of the Scout keyword does).

Perfect, thank for the reply.
