Why this bracket?

  • No hard floors (no Game Changers, no two-card infinite combo, no mass land destruction) — verdict from optimization score 19/75 (12 card draw, 5 interaction, 2 fast-mana)
  • Engine accuracy reference: 100% bracket-in-range across 36 validation decks (engine beats Claude Sonnet/Opus/Haiku on bracket-exact).

How it compares

Against the 5 Commander 2021 decks we analyzed, this is the weakest — power 3.5 versus a set average of 4.1. That is 1.2 below the 58-precon library average of 4.7. Its Tipping Point lands on turn 5, 1 turn later than the library median of turn 4.

Upgrade this precon

6 staples this deck does not already run — all legal in Zaffai, Thunder Conductor's colour identity, none over $20, and none of them a Game Changer, so none forces a Bracket 3 floor on its own. Adding cards can still move the bracket: paste the updated list back into the calculator to re-check.
