How does River Blockade's effect work if my opponent triggers locations in his marshalling and then I play down River Blockade. Obviously it can't retroactively cancel but does it cancel the next thing or do nothing until the next round?
Can I pay the cost for an event or effect without there being a valid target for the effect? ie. Kneel a maester to play Ill Tidings with no attachments on the board
I saw from our Greek friends the combo of playing Oldtown Politics to kneel a maester and then triggering Copper Link to give the event the "raven" trait to allow you to trigger Samwell Tarly. Assuming this is true, can I do this with Game of Cyvassse to kneel my maester with Copper Link and give Game of Cyvasse the raven trait? What about ambush, kneel the 2 influence maester to bring a ambush card into play and give it the raven trait to trigger Samwell?
Thanks
