With all the recent talks about overpowered cards and NE houses, it might be interesting to discuss what each house's weaknesses are. These could be bad match ups, cards, mechanics, etc. Since I primarily play Martell and Targ, I'll throw out my thoughts on those.
Martell
- Winter, and especially the winter agenda. Winter hampers card effects (maesters/open market), reduces gold to mitigate Martell's card advantage, and (with agenda) eats into their hand size.
- Event/triggered effect cancels
- "Weenie" character control (burn, Venomous Blade, Payne, and Grey Wind are great against Martell)
Targ
- High-STR characters (especially non-unique, since second and third copies are still playable after the first dies)
- "Weenie" character control
- Location control, or other forms of resource denial (to take out influence AND gold)
