I am thinking of ways to abuse Bran and I am wondering if the effects of the old revealed plot will still be in effect after I reveal a new plot. Obviously, Buidling Season's effect takes place when revealed and then it doesn't matter (i.e. it isn't undone) if Bran lets me reveal a new plot. How about Mutual Enemies though? If a new plot is revealed after Mutual Enemies is revealed does the "You and that opponent cannot declare MIL challenges against one another this round." stick around or is it null and void because that plot is no longer in play? What about Snowed Under? Is the effect "At the beginning of the standing phase, choose one kneeling character or location controlled by each player. Return all chosen cards to their owner's hands" setup when the event is revealed or when we get to the beginning of the standing phase if Snowed Under is no longer the current event it's effect doesn't happen?
Thanks,
