Your opponent controls an active Dragonpit (characters controlled by opponents who do not have more cards in Shadows than you do get -1 STR.).
You play Daenerys Targaryen (GotC). 3 printed STR and
characters you control get +1 STR.
Can your opponent respond with Pyrophobia? (Response: After a character's STR is reduced to 2 or lower by a card effect, return that character and all attachments on it to their owner's hand.)
It is like the Bolton Refugee/Winterfell Castle/Dreadfort situation, where Pyrophobia can not be played because at the point of the response Dany's STR is 3?
