I don't know if this is the right place to submit this suggestion, but since facing Yuriko in Historic Brawl is one of the most awful gameplay experiences I've ever had during this years playing Arena, I'm gonna do this anyway:
IT SHOULDBE BANNED AS COMMANDER (or nerfed).
It has basically no answers in the early game, especially when I'm playing “slower” decks (and by “slower” I mean I'm not already far ahead on turn 2 with a huge board and tons of removals in my hand). It's so much consistent and it gives so much value that it's almost impossible to keep up the tempo against these decks.
Also, most of the cards that are usually meant to stop Commanders like Yuriko are banned in the Historic Brawl format: Pithing Needle, Sorcerer's Spyglass, Disruptor Flute, they're are all - although righteously considering the overall gameplay experience - unavailable in the format.
Please, do f-ing something about this.
The format is basically unplayable right now.
Thanks
