We quickly found that the Mono White Control list we had in our team was seemingly beating everything. The addition of the two previously mentioned cards made its Rakdos-based matchups much better, while its Esper Legends matchup also improved significantly thanks to the new sweeper.
You used to have to play Depopulate, which was simply a bad card, so the upgrade to Sunfall was massive.
The Reanimator matchup also improved as they moved away from Atraxa, Grand Unifier and opted for Etali, Primal Conqueror instead. Etali often hit blanks from the Mono White deck as it would mill a Lay Down Arms or an Ambitious Farmhand.
However, even though most of us believed that Mono White Control was the best positioned deck, we were all worried about going to time – especially if other teams also recognized that this deck was great and played it, since the mirror was almost impossible to finish within fifty minutes.
I believe this was the biggest mistake we made in our preparation, and it was a tremendously costly one.
Ultimately, Mono White would have been extremely well positioned at the Pro Tour, and I think the list we had was better than what the few Mono White players had at the Pro Tour (though I do think Autumn Burchett’s list was the best – splashing for Duress and Breach the Multiverse was genius).
The deck was also near non-existent in the field, and Domain Control was not very popular either, which was our other worry about playing the deck.
What we should have done was get over our fear about going to time by practicing a lot with the deck, so all the common lines became second nature to us, and then the time factor wouldn’t have mattered as much. But we didn’t take the plunge, and it cost us dearly.
