T: Name a card. Opponent reveals X cards from his or her hand at random, or entire hand if he or she does not have enough cards. Opponent then discards any of those cards that match the one you named. May only use this power during your turn.

You don’t name a card until the ability resolves. Once you name a card, it’s too late for the targeted opponent to respond.

You may activate the ability only during your turn, but you may do so any time you have priority. (In other words, it’s not restricted to only the times you could cast a sorcery.)
