2Bracket

2 · Core by the list. The bracket comes from Wizards' card rules alone; the colour says how well the deck does what Bracket 2 allows.

The three dials average 89 for what Bracket 2 allows: that sets the colour.
Power 22 counts as 88 here: Bracket 2 is for Power 25 and up. With Manabase 94 and Health 86, that is 89 on average (weights 40 / 30 / 30).
No Game Changers, mass land denial or pile of extra turns: Core by the list. Exhibition (1) is about what a deck is for, and only you can say that.
Combos are not checked yet.

22Power

How fast and how hard this deck can take over a game. Absolute: about 90 and up is cEDH, so a casual deck scores low on purpose.

Casual

Average mana value 3.87: it acts late
14 cards that draw or dig
No tutors: it sees its best cards only by drawing them
3 answers at mana value 2 or less
1 piece of fast mana: Sol Ring

94Manabase

Can it cast its spells on time, in its colours?

Excellent

6 lands always enter tapped
40 lands, counting ramp ≈ 42 sources: enough for mana value 3.87
Every colour has the sources its heaviest cards want

86Health

Does it have the parts every Commander deck needs: ramp, cards, answers, and a curve it can cast?

Good

9 spells cost 6 or more (15% of spells; aim under 10%)
Only 8 ramp pieces (aim for 10)
Only 7 ways to remove a threat (aim for 8)
14 cards that draw or dig ✓
3 board wipes ✓

Scores read the list alone, from each card's own rules text: they can't see how a deck is played. Bracket names and the Game Changers list are Wizards of the Coast's (Commander Brackets, list as Wizards last changed it, 9 February 2026).
