By the time of Magic World Championship XXVII, I thought there were two clear best decks — Izzet Epiphany and Mono-Green Aggro❄ — with Mono-White Aggro❄ as a close third and nothing else in the same ballpark. Since then, Mono-White Aggro❄ has been putting up better and better results, to a point where I think we can say there are now three decks in Tier 1. These decks all have relatively even matchups among themselves and are overall favored versus the amalgamation of the rest of the field.
For reference, here's the deck Rei Sato and his teammates played at Magic World Championship XXVII:
- 4 Luminarch Aspirant
- 4 Usher of the Fallen
- 3 Reidane, God of the Worthy
- 4 Elite Spellbinder
- 3 Stonebinder's Familiar
- 4 Intrepid Adversary
- 4 Sungold Sentinel
- 3 Adeline, Resplendent Cathar
With the release of Innistrad: Crimson Vow, all three Tier 1 decks have gained new tools, but I think Mono-White Aggro❄ gained the most by far. When a deck that was already one of the best decks in the format gains powerful new tools, we have to pay attention.
