I never change my looping team out for another team and I can win against almost every team. Why? Because I have a cleanse.
But it’s not that simple. You also have to be careful and pick your battles for four of a kinds.you should not use any looping that will hurt your team rather than help it. You should have a utility troop on your team that can either mana drain or stun or freeze to combat her and her skill/traits. (Freeze doesn’t directly combat Mab but it combats her allies which helps take away their extra turns too)
This freeze ability of Mab’s is not OP. Mab has very hard counters… Stun, cleanse, mana shield, and impervious are the obvious ones.
And if you are fighting against a queen Mab team without a cleanse, stun, mana drain then you should ADD one/make an alternative team to counter her. Or you should expect your win rate to be lower against her. If your team still wins most of your fights, then a few queen Mab losses isn’t a big deal.
In short, I think Queen Mab’s frozen trait is fine and is the only thing left that makes Mab unique and sometimes complicated to go against.
Also, frozen should freeze that color from being used. And correct me if I’m wrong (maybe this is a bug I’m experiencing) but there are a Lot of times where in a cascade if a 4 of a kind of a non-frozen troop drops after the AI does a 4 of a kind of a frozen troops color… The freeze is negated. I find that odd since the team was already frozen and the turn was supposed to be conceded… But anyways there’s that.
Also, it seemed like the freeze only worked with the fill order. For example, troop 1,2,3 is blue. Troop 3 is frozen. Person picks a 4 of a kind blue, and still got an extra turn because the blue never reached the 3rd troop. Again, maybe that’s just something I was experiencing, like a bug, but that’s what it seemed like to me. I never paid too much attention afterwards and I didn’t document it so there’s a chance I could be wrong but that’s just how I remembered it after a few battles of it happening in.
Perhaps that was because of a person with freeze immunity? I wonder if that interaction could be caused because of that. Not sure
