Its winter

I have The Wall in play (Bara version)

I have Castle Black in play

I play a highgarden refugee

Does this allow me to trigger Castle Black to reduce, say, Core Aemon (I know it won't extend to bara cards in my hand)

What if Castle Black was passive?

I have concluded yes on both counts. I just want to confirm.

Nights watch rules.

Yep, that works. See this thread:

I don't think there'd be a difference if Castle Black's effect was passive.

I hope my metagame is ready for every plot being able to drop Starve For Your King and The Raven's Message thanks to The Stormlands. Oh yeah.
