What happens if an opponent has triggered OSB against me and I then win a challenge with the Carrion Bird?
Does the CR response (Cannot be cancelled) still get triggered and does this use up one of the 3 next effects that OSB refers to?
If it is Summer, discard Oberyn’s Shield Bearer (cannot be saved) to cancel the next 3 effects triggered by a single opponent (of your choice) this round.
After you win a challenge in which Carrion Bird participated, shuffle any number of Raven cards from your discard pile,one card with the printed Raven trait from play, back into their owner's decks. (Cannot be canceled.)
