Bracket 3 by the list · Upgraded
Blue: the colour is how well it does what Bracket 3 allows.
- The three dials average 67 for what Bracket 3 allows: that sets the colour.
- Power 27 counts as 54 here: Bracket 3 is for Power 50 and up. With Manabase 79 and Health 73, that is 67 on average (weights 40 / 30 / 30).
- 1 Game Changer (Core allows none; Upgraded up to three): Farewell
- cEDH signals: 1 piece of fast mana · 0 tutors that find any card · 0 free spells
- Combos are not checked yet.
Power 27: why
- Average mana value 3.70: it acts late
- 32 cards that draw or dig
- No tutors: it sees its best cards only by drawing them
Manabase 79: why
- 14 lands always enter tapped
- 23 sources make green, and it has a card costing {G}{G}{G}: aim for about 30
- 37 lands, counting ramp ≈ 41.5 sources: enough for mana value 3.70
Health 73: why
- Only 2 ways to remove a threat (aim for 8)
- 10 spells cost 6 or more (16% of spells; aim under 10%)
- 11 ramp pieces ✓

Led by Morska, Undersea Sleuth. A white-blue-green Commander deck built around artifacts and token swarms. 32 creatures, 37 lands, average mana value 3.70.
