With what little info we have from YCS Mexico City, it seems that what most people predicted of the April format pre-Primal Origin is true so far: Geargia and Bujin and going to be on a roll. Both decks were somewhat obvious choices for success in the format since neither of them lost anything significant to the banlist (if at all).
Now, since I find both of these decks incredibly unfun to play against, I decided to take a break from serious competition at locals for the time being. But I realized that I can't stay away forever, and that Geargia and Bujin will likely still be at least somewhat relevant even after PRIO drops.
So that made me start to wonder: what decks even have good matchups against both Geargia and Bujin? I started a thread on Pojo specifically to ask people this question.
