Commander brackets
What the bracket engine counts, the five levels and their caps, and what it cannot see.
Silvane evaluates a Commander deck against the official 1 to 5 bracket system and reports the lowest bracket the deck fits in.
- In the app — Data → Bracket. It also appears on Brawl decks.
- In the Studio — the Legal tab, plus a chip in the top bar reading Bracket 3 · est. 2 when you have declared a level above the calculated one. The Studio computes brackets for Commander only.
The three signals
The engine counts three things, and nothing else:
| Signal | What it counts |
|---|---|
| Game Changers | Cards on the official Game Changers list |
| Mass Land Denial | Cards that break everyone's mana |
| Extra Turns | Cards that take another turn |
The five brackets
The engine walks 1 to 5 and stops at the first bracket whose caps are all satisfied. That is the calculated minimum.
| Bracket | Game Changers | Mass Land Denial | Extra Turns |
|---|---|---|---|
| 1 Exhibition | 0 | 0 | 0 |
| 2 Core | 0 | 0 | 3 |
| 3 Upgraded | 3 | 0 | 3 |
| 4 Optimized | any | any | any |
| 5 cEDH | any | any | any |
Why not bracket N? names the signal that blocked the bracket below, card by card.
What it cannot see
Two-card combos are not detected. Silvane does not enumerate two-card synergies, and says so on the screen: "If your deck has them, set your intended bracket manually to disclose."
Your intended bracket
Set an intended bracket on the deck to declare your own level. When it is higher than the calculated one, the deck shows the higher of the two, so it never advertises itself below what its cards say.
Brackets are a table-talk tool, not a sanctioned rating.
