Standard is starting to coalesce into a somewhat stable metagame of Sultai Midrange, Mono-Red Aggro, Izzet Drakes, Azorius Aggro, Mono-Blue Aggro, Esper Control, and various takes on Nexus of Fate, but I'm not ready to stop brewing and learn a stock deck. I probably should – those decks are great and there's room in all of them to learn them well and tune them – but there's still so much more to explore. I just loved brewing before a Pro Tour, and I expect to continue to love brewing before a Mythic Championship, so I'd like to share some of the ideas I've been thinking about.
I like Dovin, Grand Arbiter in creature decks that attack well. I started by exploring with using it with Hero of Precinct One, but I wasn't really that impressed with the Hero. It was just too likely to die and the 1/1s didn't matter unless you were working pretty hard to find a way to use them productively since they don't attack especially well. I wanted to find a deck that was better at using Dovin, so I'm currently thinking about Azorius Skies.
