2 players, A and B

In the challenge phase, Player A has a card coming out of shadow, it has a response (1).

Then Player B has a card coming out of Shadow, it has a response (2).

One question, when will response (1) get responsed?

After Player A's shadow card coming out of shadow area or after Player B's?

Cards are brought out of Shadows separately and - according to the rules - in their own windows. So any Responses to card #1 coming out of Shadows are triggered before card #2 has the chance to come out of Shadows.

thank you ktom.
