Hello!

Baelor Blacktyde has a text "Opponents cannot play copies of event cards that are in their discard pile." How does this card interact wth shadow events?
In Shadows rules it said "After an event card comes out of Shadows, it is treated in the same manner as a non-Shadows event card played from a player’s hand." Does it mean that Shadow event is considered being played?

For example: my opponent has Baelor Blacktyde in play and I has a copy of Fiery Kiss( Response: After Fiery Kiss comes out of Shadows, choose 1 non-Army character in your dead pile and put it into play. That character gains vigilant until the end of the phase. At the end of the phase, discard the character if it is still in play. ) in my discard pile and copy of Fiery in Shadows. Can I bring Kiss out of Shadows and trigger its response, presuming I have valid target in my dead pile?

no no no no no

To fill in some of the detail, Shadow events behave a little differently than regular events (so bear with me a bit on this explanation).

Normally, triggering the effect on an event card and playing from your hand are part and parcel of the same thing. That is, you cannot trigger the event's effect without playing it from your hand.

However, Shadow cards are a little different. Bringing them out of Shadows is considered a separate thing from triggering any of the effects on the card. For example, you could bring Fiery Kiss out of Shadows and then choose not to trigger the Response (kinda silly if you do, but it is possible).

So, bringing an event card out of Shadows is not the same thing as playing the event. Effects that put limits on playing event cards do not put those same limits on bringing events out of Shadows. (So Baelor Blacktyde does not stop you from bringing an event card out of Shadows that is already in your discard pile. You are not "playing" the event, so he doesn't apply.)

The rule that, once out of Shadows, event cards count as if they were played from your hand makes the effects on Shadow events vulnerable to things like Paper Shield, as well as letting the Shadow event satisfy "after you play an event" Responses, but that "equivalence" does not become applicable until after the card is brought out of Shadows (so again, Baelor would come too late).

So, there's the reasoning. The short answer is "Baelor doesn't do anything to Shadow events."

Thanks, ktom. Especially for reasoning.))
