Setup
1. Card data
Checking…
A one-time download of about 25 MB from Scryfall: card text, legality and Game Changer flags. Everything after that runs offline. Update it when new sets or ban-list changes come out.
2. Opponents
Checking…
Popular public Commander decks, ten per bracket, from Archidekt. Your deck plays against them so it isn't only tested against copies of itself. Takes a few minutes; needs card data first.
3. Combos
Checking…
Known combos from Commander Spellbook, about 29 MB. The bracket estimate counts the two-card ones, each deck page lists the ones it contains, and quick estimates treat the ones that win as wins. Without it, a short built-in list is used.
The checks pit reference decks against each other where the right answer is known: each seat should win about as often, the same run should repeat, a deck with its spells swapped for lands should lose more, and higher-bracket decks should beat lower ones. A mode that fails is only good for a first look.

Real games are slow. This plays a few on your machine to find how many it can run at once.
Forge is not installed in this environment, so there is nothing to test. Use the Docker image, which bundles it.
