Why this bracket?

1 Game Changer — crop rotation. Per WotC framework, any Game Changer forces a Bracket 3 floor minimum.
1 Game Changer detected (any = Bracket 3 floor; Bracket 3 allows up to three)
Borderline verdict — close to B2: Bracket 3 solely on a single Game Changer (Crop Rotation) — otherwise plays at Core pace (goldfish ~turn 8), no combo or fast clock
Engine accuracy: 77.1% exact and 99.5% within one bracket on 1,229 organizer-labeled tournament decklists (engine v389).

How it compares

Against the 5 Commander 2020 decks we analyzed, this is the strongest — power 5.9 versus a set average of 5.1. That is 1.3 above the 174-precon library average of 4.6. Its Tipping Point lands on turn 4, the same as the library median.
