An idea I've been wanting to try out, a Nightswatch choke deck that oppresses the opponents gold and their reserve while you gain all the gold through things like Littlefinger, Eastwatch Carpenter, White Tree, Meager Contribution and The Roseroad. Meanwhile you also have cost reducers which in turn help build up your board more, combo'ing Brandon's gift, into Sworn Brother, into Steward at the Wall (for free) who then kneels to help you play Shadow Tower Mason which then lets you play Queenscrown (for free). This move would normally cost seven gold, but now only costs you five gold. As shown there are multiple ways to gain more gold and thus despite the low income plots this deck theoretically shouldn't have a low income. Combine the fact that it's a King of Winter agenda, you should be oppressing your opponents income and their card pool too.
