Despite Esper Control receiving some of the top billing from SCG Richmond, Esper Midrange is the better deck, and it's not particularly close.
Across the board, Esper Midrange has better matchups against Mono-Red Aggro, Simic Nexus, and green midrange decks. You suffer somewhat against Esper Control, at least in Game 1, and the white aggro decks are slightly worse than they would be with Esper Control, but Esper Midrange is also fundamentally stronger.
Keep in mind that last weekend, Esper Midrange decklists were all over the place. They didn't know what to expect or what they needed to prepare to beat. Now that that's out of the way, we can truly build a monster. Why do I believe we can actually do that?
The secret is that Esper Midrange is G/W Tokens in disguise. To get a better idea of why that's relevant, you should read some of my articles on that deck if you haven't already. The play patterns are remarkably similar and the overall strategy for both archetypes is exactly the same.
In order for that sort of deck to work, it needs to be able to never run out of gas. You continue pushing your advantage, accruing value, and eventually win the game. I'm important to not spew resources if you can help it and to not take aggressive lines unless you know they will translate directly into a win or unless you have no other options. Slowly cut off your opponent's outs by developing different threats and eventually you'll bury your opponent.
With all the planeswalkers in the format, traction is incredibly important, which is one of the reasons I value having creatures in my deck. Good, cheap threats are particularly strong against the various three-mana planeswalkers, whereas Esper Control has to Vraska's Contempt them or fight through them with their own card advantage. Overall, it's a tall order. As always, I'd prefer to be more proactive.
I started working on Esper Midrange because I didn't see a world where Absorb was a playable Magic card in the face of all the Teferi, Time Ravelers, and I'm glad I did. After a week of testing and tuning, I can share this beast in time for SCG Syracuse.
