cEDH League: How to Track Competitive Commander on Nerd Leagues

A cEDH league on Nerd Leagues is a regular league configured for competitive Commander — same EDH format, but with the settings, seasons, and dispute tools that competitive groups actually use. The big shift from a casual pod isn’t the format; it’s that deck ELO becomes the rating that matters most, and that getting the result right matters because someone’s standings move when the game closes.

If you’re running a casual pod, the playbook is in Commander Pod League. Stick with this article if your group is bringing tuned cEDH lists to the table.

Set up a cEDH league

cEDH leagues use the same league-creation flow as any other league. From the nav, open My Stats and create a league. Three fields:

• Game — leave it on Magic the Gathering.
• League Name — name it after the group or the venue (e.g. Garage cEDH, NYC cEDH Tuesdays, Spike Hours). The invite code derives from the name automatically, so a focused name produces a clean code.
• Description — a one-liner about expectations works (“Tuned cEDH only, no proxies above $20, B&R as official”). Saves you from explaining the rules in chat every time someone new shows up.

The full creation walkthrough is at How to Create a League.

Configuration choices that matter for cEDH

Open Manage League and tighten a few settings that casual pods would leave loose:

• Invite Code — the auto-generated code is fine for most groups. If your league is invite-vetted, treat the code like a doorman pass: don’t post it publicly, share it only with players you’ve cleared.
• Allow any member to invite players — turn this off for vetted leagues. Disabling it means only you, the commissioner, can use the in-app Invite Friend button. (The shareable invite-code link still works for anyone holding the code, so this isn’t a hard lock — just a friction layer that prevents accidental member-driven invites.)
• Discord Webhook URL — paste your league’s Discord webhook here. Every recorded game posts to the channel, plus flag events, so disputes show up in front of the whole group automatically. There’s a Test button to confirm the webhook fires before you save.

The full set of commissioner powers, including member kicks and game management, is documented at The Commissioner Role.

Format and sub-format for cEDH games

When recording a cEDH game, the format and sub-format dropdowns on the record-game form are what differentiate it from casual EDH:

• Format — EDH. There’s no separate “cEDH” format; it’s the same format ID, the same K-factor, and the same ELO logic. What makes it cEDH is your league’s vibe and rules, not a database flag.
• Sub Format — pick what you actually played. Most cEDH games are Multiplayer (the four-player free-for-all). For 1v1 cEDH nights, switch to 1v1; for the rare three-player or six-player chaos, use Multiplayer with the player count adjusted.

The full format and sub-format reference is in Recording an MTG League Game.

Why deck ELO matters more than player ELO in cEDH

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, but they live in separate scoreboards. In a casual pod, deck ELO is a curiosity. In cEDH, it’s the rating most groups actually argue about — pilots can swap decks across the season, and what’s interesting is which 100-card piles are climbing the standings.

Both ratings start at 1000 and build from there. The math is the same as the rest of the league system; see MTG League ELO for the K-factor breakdown by table size. The league page splits them cleanly: Members for player rankings, Decks for deck rankings.

Recording cEDH games

Use the same record-game flow as any league game: Play Game in the nav → Already Played → pick the league, format, sub-format, players, decks, and winner. The first time a player records a cEDH game with a given deck, the deck auto-registers in your league — you don’t add it manually. Mechanic detail is in Adding Decks to an MTG League.

Two cEDH-specific tips:

• The Notes field accepts [[Card Name]] shorthand. Capture the finishing line in writing — “T3 win, [[Thrasios, Triton Hero]] / [[Tymna]] flash hulk into [[Thassa’s Oracle]]”. The notes render as styled card links on the game page, which makes scrolling old games much faster.
• Knockouts are stat-only. The recording form lets you mark who knocked whom out. That gets stored for stats, but it does not affect ELO — only the winner-vs-loser outcome moves ratings. Don’t argue about knockout credit hoping it will change someone’s number.

Run a cEDH season for competitive cycles

cEDH metas move on quarterly cycles — new commanders, new decks, new B&R touches. Seasons let you carve those cycles into discrete scoreboards: a Spring 2026 season runs from April through June with everyone reset to 1000, then ends, and the next season opens. Per-season ELO is independent from the league’s all-time ELO, which keeps both views useful: long-term skill and short-term meta dominance, side by side.

Conceptual details are in MTG League Seasons; the create/edit walkthrough is in Creating and Managing MTG League Seasons; the reading guide is in Season Standings. Seasons can also overlap — a quarterly inside an annual — and the rules for that fan-out are in Overlapping MTG League Seasons.

Resolving disputed results

cEDH is the format most likely to need a dispute path, because games hinge on rules interactions and people care about the result. Nerd Leagues handles disputes through the flag system on the game page:

• Any participant in a recorded game can flag it. 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. Submit, and the flag fires a notification to the commissioner (and posts to the league’s Discord webhook if one is set).
• Each user can flag a game once. Multiple participants can pile on the same flag with their own context, but no one can flag the same game twice.
• Commissioners resolve flags from the game page with three options: Dismiss Flag (keep the game as recorded), Edit Game (correct the data — note: this does not trigger an ELO recalculation), and Archive Game (soft-delete, which does trigger a full ELO recalculation). If you fix a wrong winner via Edit, run the admin ELO recalc afterwards to bring standings into line.

Commissioner powers across the whole flag flow are documented in The Commissioner Role.

Where to go next

Bookmark your league page and pin the invite code somewhere your players can find it. The big sibling articles for cEDH commissioners are MTG League ELO for the rating math, Season Standings for reading per-season tables, and The Commissioner Role for everything that lives on the Manage League page. If your league plans to publish standings outside the group, the public-vs-private breakdown is in Public vs Private Leagues.
