Commander precon · Foundations Commander · 2026 · led by Sai, Master Thopterist
Main theme: Card draw · Synergy 4.2/5 (tight) · Bracket 1–2 · Sai, Master Thopterist works with 45 of its cards
Upgrades at bracket 1–2
No Game Changers and no infinite combos: the level of an unchanged precon. Game Changers are cards on WotC's official list of cards that make a deck much stronger.
1 swap, and after them the report reads the deck at bracket 1–2.
Its cards work together a little more: synergy 4.2 → 4.3 of 5, still tight. Its consistency is unchanged: Build stays at 4.3 of 5, on target; 4 short on ramp, was 5, still 2 short on interaction. That is what this page measures: how well the deck holds together, not how strong it is.
Ramp
- Take out Memory Guardian: Memory Guardian is next on the report's cut list. Works with 19 other cards: with 12 again and again, with 7 just once or in the background. Put in Phial of Galadriel: Ramp: you were 5 short; Phial of Galadriel counts as ramp. While you control Phial of Galadriel, Adaptive Omnitool counts it and gets bigger.
Upgrades at bracket 3
Up to three Game Changers, and no two-card infinite combo that costs 6 or less.
5 swaps, and after them the report reads the deck at bracket 3.
Its cards work together a little more: synergy 4.2 → 4.5 of 5, still tight. It is a little more consistent: Build 4.3 → 4.4 of 5, still on target; still 2 short on interaction, 2 short on ramp, was 5. That is what this page measures: how well the deck holds together, not how strong it is.

Interaction
- Take out Counterspell: Counterspell is weaker counterspell than Force of Will. Put in Force of Will: Force of Will is counterspell too, and one of the strongest cards in Commander: a Game Changer, which this bracket allows.
- Take out Negate: Negate is weaker counterspell than Fierce Guardianship. Put in Fierce Guardianship: Fierce Guardianship is counterspell too, and one of the strongest cards in Commander: a Game Changer, which this bracket allows.
Board wipes
- Take out Aetherize: Aetherize is weaker board wipe than Cyclonic Rift. Put in Cyclonic Rift: Cyclonic Rift is board wipe too, and one of the strongest cards in Commander: a Game Changer, which this bracket allows.
Cards that work together
- Take out Whirler Rogue: Whirler Rogue works with 4 cards in this deck, 2 of them on its theme; Uthros Research Craft works with 46 cards, 44 of them on it. Put in Uthros Research Craft: While you control Uthros Research Craft, Adaptive Omnitool counts it and gets bigger
Upgrades at bracket 4–5
No limits on Game Changers or combos.
5 swaps, and after them the report reads the deck at bracket 3. These are the same swaps as at bracket 3: none of the stronger cards bracket 4–5 allows does any of these jobs strictly better, so aiming higher changes nothing for this deck.
