X-Agenda decks suffer a lot control deck.
Martell Red Viper Summer deck for example. Recycling bleeds with open market. Valar. Wildfire.
Same thing with Targaryen control with the hill. With my deck I lost lots of time against this archetip played by dondiego.
In the other hand I think that the bad thing is that you have to create at the moment a deck against it. So maybe the targaryen control deck worked not so good against other archetip.
The new agenda will for sure create great deck but very skilled people. Bleeds will be for free. Maybe too proud to bow will se more play (think about the fact also brotherhood are neutral) and the agenda will help this event to be played.
The idea of Rogue can work. But at the moment I think 3 limits can do better.
In this way if you need stealth you concentrate on wildlings (for example will greyjoy riders). If you need icons and want to play some key char in house: Jon Snow, Benjen you play NW agendas. Paying 4 a 8 army deadly triicon is very good but not "banneble".
