2450+ in pro play. Sadly, might be able to be made better by adding Renfri, but Novigradian Justice is still a good card as is Zoltan's Company.
I think the meta is decently control oriented which makes all the armor pretty good. And honestly, Dwarves are pretty resilient against Renfri too. Her high roll seems to be the damage abilities, dealing 1 to all units or 2 if their base power changed, along with 8 damage to all enemy units. This deck negates most of that and helps limit the upside of her abilities (which is still way too much, but might she might only be looking at 25 point plays instead of 40).
If anyone is interested, I also have a successful Symbiosis deck I'm using this season (Eithne is insane in round 3 and the deck has high tempo due to its leader) as well as a mutagenerator golden nekker NR deck, because fuck the meta.
