I understand that Theon triggers his abiltity at the start of dominance
If an unique characer is discarded, he retuns to play and is counted in dominance
Do other responses get triggered at the same time (I assume they do)
Specifically Support of Salcliffe
Response: After 1 or more cards are discarded from an opponent's deck, stand attached character.
So if an unique character is discarded, Theon would enter play and I would also stand any characters with SoS attached - all those characters would count their strength for domiance
Side question - Moyley Crewman
His text implements a constant effect to discard one extra card
Any effect that discards 1 or more cards from an opponent's deck discards an additional card
Does this constant effect apply to cards out of play, such as Theon
