Pro Tour testing has begun. Standard is on everyone's mind and all eyes are on the Magic Online 5-0 decklists. In the meantime, my good friend Eliott Boussaud played and won the online PTQ, without dropping any of his 12 matches, to qualify for Pro Tour Cleveland. His weapon of choice? B/G Midrange.
Seth Manfield already walked you through the basics of Golgari, but the main difference in Eliott's list is the inclusion of four Doom Whisperer. Just like the explore creatures, it allows you to create your own toolbox by dumping cards you'll later be able to retrieve with either Golgari Findbroker or the Find half of Find // Finality.
Its synergy with Izoni, Thousand-Eyed is very powerful. If you manage to play the Nightmare Demon with a healthy life total and not too much pressure on the opposing side of the board, you should be able to fill your graveyard with your early creature drops (explore creatures and Llanowar Elves) and cash them in for Insects with Izoni.
A 6/6 flyer is no joke. You usually don't want to pay five, even for a huge body, without an instant payoff, but its ability makes up for it by finding a card that will get you the payoff you're looking for. In the mono-red matchups, you'll be able to contain the early game and finish the game quickly with a Whisperer without durdling around for too long.
According to Eliott, Doom Whisperer is probably the best card in the deck and he doesn't see any reason to cut any from the deck, or even sideboard one out in any matchup.
His list is probably not the most adapted list to play the mirror. I got to face Carnage Tyrant a couple of times for example and I didn't think it would be that hard to beat. The Tyrant is a great answer to other control matchups, including Grixis or Jeskai, so maybe you want to have a few of them in your board.
If you plan to play B/G Midrange, you'll have to practice the mirror a lot. I played leagues where I faced the same deck five times in a row. It's a matchup where you're trying to establish control by having a big threat stick to the board (mostly a Planeswalker) but that can also be swung in specific situations by the Finality half of Find // Finality or Izoni, Thousand-Eyed. The problem with Doom Whisperer is that you can't really play it when your opponent has a Vraska, Relic Seeker or a Vivien Reid out as it only takes one activation of either of them to take it down.
I played a few leagues with the deck and it does feel good. Its early game is able to apply pressure, helps you to find lands for the later game and can even gain you life. Its late game is also powerful with Doom Whisperer and Vraska, Relic Seeker. Doom Whisperer ensures you follow it up with another powerful spell.
It's very consistent for a deck running four five-drops and four six-drops, but it's possible for them to glut in your hand while you're waiting for your fifth land drop, and that's usually how you lose. Every turn has a lot of different decisions, how to play your explore creatures, in which order, what to do with your Planeswalkers, surveil or not… so it's just more room to mess up.
Things go fast in this new Standard format, so I wouldn't be surprised if this list became obsolete quickly. So try it out while it's good! In any case, B/G Midrange is one of, if not the best deck in the format, so you might as well get used to it now.
