cEDH League: How to Track Competitive Commander on Nerd Leagues

A cEDH league on Nerd Leagues is a regular league set up for competitive Commander — the same EDH format, with the settings, seasons, and dispute tools a competitive group tends to need. Commander Pod League covers the casual setup.

Set up a cEDH league

cEDH leagues use the same creation flow as any league. Open My Stats and create a league. Three fields:

• Game — Magic: The Gathering.
• League Name — name it after the group or venue (Garage cEDH, NYC cEDH Tuesdays).
• Description — a one-liner about expectations ("Tuned cEDH only, no proxies above $20, B&R as official") saves re-explaining the rules in chat.

How to Create a League is the full walkthrough.

Configuration for a vetted league

Open Manage League:

• Invite Code — auto-generated as a card name plus four digits (lightning-bolt-4729), which is not guessable. You can replace it with anything URL-safe; a code you choose is only as private as the string you pick.
• Allow any member to invite players — turning this off leaves the in-app Invite Friend button to the commissioner alone. The shareable invite-code link still works for anyone holding it, so this limits in-app invites rather than sealing the league.
• Discord Webhook URL — every recorded game posts to the channel, plus flag events, so disputes surface to the whole group. A Test button confirms the webhook before you save.

The Commissioner Role documents the full panel, including member management.

Format and sub-format for cEDH games

• Format — EDH. There's no separate cEDH format: same format, same K-factor, same ELO math. What makes a league cEDH is its own rules and expectations, not a setting.
• Sub Format — Multiplayer for the four-player free-for-all, 1v1 for duels. Adjust Number of Players for larger tables.

Recording an MTG League Game lists the full format and sub-format options.

Deck ELO and player ELO

Every recorded game updates two ratings: the player's per-league ELO and the deck's per-league ELO. They use the same formula and the same K-factor and live on separate scoreboards, so a pilot who swaps decks mid-season carries one rating while each list builds its own.

Both start at 1000. The league page splits them: Members ranks players, Decks ranks decks. MTG League ELO has the K-factor breakdown by table size.

Recording cEDH games

Same flow as any league game: Play Game → Already Played → pick the league, format, sub-format, players, decks, and winner. The first time a player records a game with a given deck, that deck registers in the league automatically — see Adding Decks to an MTG League.

• The Notes field accepts [[Card Name]] shorthand. "T3 win, [[Thrasios, Triton Hero]] / [[Tymna the Weaver]] flash hulk into [[Thassa's Oracle]]" becomes card links on the game page.
• Knockouts are recorded for stats only. The form lets you mark who knocked whom out. That's stored and displayed, but only the winner-versus-loser outcome moves ratings.

Seasons for meta cycles

Seasons carve the calendar into separate scoreboards: a Spring 2026 season runs April through June with everyone reset to 1000, then closes and the next one opens. Per-season ELO is independent of the league's all-time ELO, so both views stay readable.

MTG League Seasons covers the concept, Creating and Managing MTG League Seasons the controls, and Season Standings how to read one. Seasons can also overlap — a quarterly inside an annual.

Resolving disputed results

Disputes go through the flag system on the game page:

• Any participant can flag a recorded game. Open the game page and click Flag Game. The modal asks for a reason — Wrong Winner, Wrong Players, Fake Game, Wrong Deck, Wrong Format, Duplicate, or Other — plus optional details. Submitting notifies the commissioner and posts to the league's Discord webhook if one is set.
• Each user can flag a game once. Several participants can flag the same game with their own context; no one can flag it twice.
• Commissioners resolve from the game page. Dismiss Flag keeps the game as recorded. Edit Game corrects the data without recalculating ELO. Archive Game soft-deletes it and triggers a full ELO recalculation across the league.

Because Edit Game leaves ratings alone, correcting a wrong winner through it will leave the standings reflecting the old result. Archiving the game is what moves the ratings; a full site-wide ELO rebuild is admin-only, so ask an admin if the standings need one.
