Compelled by the Rock says "move that attachment to another card you control"
I take it that I can move a character attachment to a location - and then the attachment is illegally attached and gets discarded?
Prepare for War says "any number of influence producing cards with a combined cost of 3"
Do all the cards have to have costs - e.g. could I stand someone's house card if they are running Hollow Hill agenda
Pyat Pree says "instead of the normal claim affect"
If Pyat Pree attacks alone, meeting the conditions and the defender plays Red Vengeance, I assume the Pyat Pree still gets to kill one of the defendant's characters (as the card text specifically say kill one of the defenders characters, not the person who plays the claim)
