There's a little bit of everything this week. Except for Brawl, although I expect that to change a bit once we have more results following the rules changes. Vintage is still a mess of Mishra's Workshops and Force of Wills, but thankfully there's always Pauper.
Oh, yeah, and a new Standard format.
10: Pure Control
At seemingly the last minute, R/B Aggro grew immensely popular in the blink of an eye. This lead to a lot of late scrambling by yours truly, trying to find a deck I liked for Grand Prix Birmingham. I ended up on W/B Aggro, which was a solid choice, but apparently I should have been listening to my podcast co-host, Bryan Gottlieb.
He's long been championing a version of U/W Control that mostly eschews win conditions in favor of an unbeatable late game in Pull from Tomorrow and Teferi, Hero of Dominaria. There are some time concern issues when playing such a deck, but realistically, it should be fine if you play fast enough. While you might pick up an unintentional draw here or there, your matchup against R/B Aggro, likely the most popular deck in Standard, is incredible.
Standard is basically never solved. There's always a new direction to take, and while the metagame at GP Birmingham might look awful and unfun, I assume it will be anything other than that in the coming weeks.
9: Ah, Yes, the Classic "Fog Tron" Strategy
I give Pauper a lot of crap for being a busted Legacy lite, and this deck is part of the problem, yet it still makes me happy.
If all you want to do is prevent all the combat damage while also having a three-to-one mana advantage over your opponent, this is the perfect deck. Killing your opponent is something that'll happen eventually with Mulldrifter beats, but you can also induce a maximum tilt factor by Capsize locking your opponent out of the game.
"Magic, the way Richard Garfield intended."
8: Soul Sister Infinite Elf Graveyard Shenanigans
This deck has some stuff going on.
You have the typical Soul Sisters stuff going on with Prismatic Strands to help beat up on the aggressive decks (and Inside Out combo decks), plus there's some Faithless Lootings to assist with the engine. Commune with the Gods can find Midnight Guard or Presence of Gond for the combo or Benevolent Bodyguard to protect it. Rally the Peasants is another part of the flashback engine that can help facilitate quick combo kills.
