Bracket 2 by the list · Core
Red: the colour is how well it does what Bracket 2 allows.
- The three dials average 54 for what Bracket 2 allows: that sets the colour.
- Power 11 counts as 44 here: Bracket 2 is for Power 25 and up. With Manabase 66 and Health 57, that is 54 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.
Power 11: why
- Average mana value 4.23: it acts late
- No tutors: it sees its best cards only by drawing them
- 5 cards that draw or dig
Manabase 66: why
- 16 sources make green, and it has a card costing {G}{G}{G}: aim for about 30
- 20 sources make white, and it has a card costing {W}{W}{W}: aim for about 30
- 10 lands always enter tapped
Health 57: why
- 14 spells cost 6 or more (23% of spells; aim under 10%)
- Only 5 cards that draw or dig (aim for 10)
- Only 1 board wipe (aim for 2)

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 54 for what Bracket 2 allows: that sets the colour.
- Power 11 counts as 44 here: Bracket 2 is for Power 25 and up. With Manabase 66 and Health 57, that is 54 on average (weights 40 / 30 / 30).

11Power
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 4.23: it acts late
- No tutors: it sees its best cards only by drawing them
- 5 cards that draw or dig
- 1 answer at mana value 2 or less, and free spells: Obscuring Haze
- 1 piece of fast mana: Sol Ring
66Manabase
Can it cast its spells on time, in its colours?
Fair
- 16 sources make green, and it has a card costing {G}{G}{G}: aim for about 30
- 20 sources make white, and it has a card costing {W}{W}{W}: aim for about 30
- 10 lands always enter tapped
- 38 lands, counting ramp ≈ 40.5 sources: short of the ≈41.7 a deck at mana value 4.23 wants
57Health
Does it have the parts every Commander deck needs: ramp, cards, answers, and a curve it can cast?
Needs work
- 14 spells cost 6 or more (23% of spells; aim under 10%)
- Only 5 cards that draw or dig (aim for 10)
- Only 1 board wipe (aim for 2)
- Only 6 ways to remove a threat (aim for 8)
- Only 9 ramp pieces (aim for 10)
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).
Led by Kathril, Aspect Warper. A white-black-green Commander deck built around lifegain and graveyard recursion. 35 creatures, 38 lands, average mana value 4.23.
