Not even a peep about any cards they have an eye on in Brawl is disappointing. They talk about it being a casual, fun format where your choices matter and I really don’t understand how cards like Mana Drain, Paradox Engine & Dark Ritual (just to name a few) don’t fly in the face of that philosophy.
I recognize balancing for Brawl cannot be easy & overall I do have fun with the format but man it could be so much better if they worked on improving it. Disheartening to see that they think it’s perfectly fine as is.
Those three cards (and several others) are all cards we have looked at specifically. Based on all of our data, they do not have an outsize impact on the winrate of decks that use them. I'm not saying they're not good cards; they are. But the boost in winrate they give is equivalent to a lot of other good cards. They're not outliers.
We are actively monitoring Brawl balance for these outliers, we just don't see any large ones to act on currently
