A Baratheon player plays a lady character from his discard pile during his Melisandre's Scheme turn. He then responds to his action by putting a Royal Entourage into play from his discard pile.
I consider this play illegal, my reasoning is as follows:
A card can only break a rule, if it directly contradicts the rule and in order to break a rule the card has to state exactly how to break said rule and what to do instead.
So how do we play a card from our discard pile? We don't know what costs, restrictions or other rules apply because this scenario isn't described in the rules of the game. The phrase "as if they were in your hand" on Melisandre's Scheme describes how playing a character from your discard pile actually works. It tells us that costs, restrictions and whatever other rules we can think of are the same as if we played the card from our hand.
However, it doesn't change where the character is played from. Hence, a lady character played from your discard pile during a Melisandre’s scheme turn is not considered to be played from your hand for the purpose of triggering responses.
Please note the interaction between Baelor Blacktyde and Robert Baratheon (KotS).
Any thoughts, official rulings or antitheses?
