@desolutionist So I think it is unreasonable to presume to know where the meta is going to be going over the next 3 months from this one tournament, especially considering the 5-0 decks from the leagues. There haven't been shops in every one of those despite being a deck that is easy to include due to having very different cards from the blue decks that have been 5-0ing (this is apparently part of the consideration for which ones to include). Looking at all the lists people have been able to 5-0 with, including things like white trash for the first time since white eldrazi happened I think, a stoneblade spell queller deck, a bunch of tinker vault ket bot decks, grixis thieves, and even in this tournament RUG delver, which I know hasn't been present in a long time. It looks to me like the diversity has gone way way up.
Yeah shops may still be reasonable, but I think in no way is the idea of it as the best deck being supported by data at this juncture. I have been doing some playtesting, and while the deck still has broken draws, it is also way more susceptible to bad openers and mulligans to oblivion. This seems most important in big tournaments, and makes it in my head closer to the "prison" or chalice aggro style decks in legacy, and less like the behemoth that shops had been in vintage over the past couple years.
