My first two reactions:
I can't believe they didn't even mention Mental Misstep. That card was banned in every other format for the degenerative arms race it created, and the pressure it puts on Vintage one-drops is bad for the format IMO.
The next B&R announcement is scheduled for October 17th. Did they even look at their own calendar before announcing this date? Are they trying to keep people from attending Eternal Weekend for Vintage? The thought of potentially having to switch up my deck at literally the last minute (the B&R announcement goes into effect after the Vintage Trial but before Vintage Champs) sounds really really awful when I'm spending $1000+ (plane and hotel) to attend this event.
I'm just so stoked I made top 32 with a deck I'd been really practicing hardcore with, even if it was just for a month or so. I've never stuck with a single deck for multiple tournaments, but it seems to have paid off. I really hope I can make it next year.
