cEDH Tournament Software

Which Tool Should You Actually Use?

Running a cEDH tournament sounds simple until you try to find software that actually supports it.

Most tournament tools were built for 1v1 Magic. Standard. Draft. Two players, one winner. cEDH is four players in a pod, custom scoring, no-repeat pairings, and a meta that demands deck submission before round one. The requirements are completely different.

This guide breaks down every major tool organizers reach for - Eventlink, Challonge, Start.gg, Topdeck.gg, and MTG Super League - so you can make an informed call before your next event.


What cEDH Tournaments Actually Need

Before comparing tools, it's worth being clear about the requirements. A cEDH event - whether it's a one-day open, a multi-week league, or a series - typically needs:

Requirement Why It Matters
Multiplayer pod support (4-player) cEDH is not 1v1. You need pods, not brackets.
Custom scoring Win/draw/loss isn't enough. Points systems vary widely.
No-repeat pairings Players shouldn't face the same opponents every round.
Deck submission and legality Decklists must be locked before rounds begin.
Tiebreaker calculations (OMW%) Point ties need fair, accurate resolution.
League series tracking Multi-event seasons need cumulative standings.

The Tools, One by One

Eventlink (WPN)

Eventlink is WotC's official tournament software. It's built for sanctioned 1v1 Magic events: Standard FNM, Draft, Sealed, Pioneer, Modern.

It does not support 4-player pods, custom scoring, or any of the things that make cEDH cEDH. It's free to WPN stores but requires a WPN account to access. If you're running a community cEDH event that isn't a sanctioned store event, Eventlink isn't the right tool.

Best for: Sanctioned 1v1 events at WPN stores. Not for cEDH.

Challonge and Start.gg

Both are general-purpose tournament platforms built primarily for esports brackets and fighting game communities. They handle single and double elimination brackets well.

Challonge and Start.gg have limited multiplayer pod support and don't natively handle Swiss pairings with 4-player pods in the way cEDH requires. No-repeat pairing logic, deck submission, and OMW% tiebreakers are absent. You end up duct-taping spreadsheets to the side to fill the gaps.

Best for: Simple single-elimination brackets. Not for Swiss cEDH events or league series.

Topdeck.gg

Topdeck is one of the few platforms built with Commander and cEDH in mind. It supports 4-player pods, custom scoring, Swiss pairings, and deck submission. It has an active community in the competitive EDH space and is widely used for large cEDH Opens.

Its league series and multi-event tracking features are more limited compared to a dedicated league tool. It's primarily event-focused rather than season-focused.

Best for: One-day cEDH Opens and large community events. Good for individual events; limited for running a multi-week league.

MTG Super League

MTGSL was designed from the start to handle multiplayer formats, multi-week seasons, and the administrative reality of running a Commander or cEDH league over time.

It supports 4-player pods with Swiss pairings, no-repeat pairing logic, custom scoring (including achievement points, split pots, and custom tiebreakers), deck submission with Moxfield and Archidekt sync, and full league series with cumulative standings across multiple events. Players get live standings, match history, and stats.

Best for: Multi-week cEDH leagues, recurring event series, and any situation where you need standings to persist across sessions.


Scoring Systems for cEDH

The scoring system you choose shapes how your event feels. cEDH organizers typically use one of these three approaches:

System Structure Best For
5/1/0 5 pts for a win, 1 pt for 2nd place, 0 for 3rd and 4th Opens and events where winning matters most
Win-only 3 pts for a win, 0 for all other positions Pure competitive cEDH with no consolation points
Placement-based 4/2/1/0 or similar across all pod positions Leagues where surviving matters, not just winning

Tiebreakers should always be defined in your rules document. OMW% (Opponent Match Win %) is the standard for Swiss events. MTGSL and Topdeck calculate this automatically.


Running a cEDH League Series

A league series groups multiple events into a season with cumulative standings. Players earn points at each event and the season standings determine the overall champion.

This format creates long-term investment that single events can't match. Players track their season standing between events, come back for the next one, and build rivalries with the same opponents across months.

Setting one up well requires:

  • Consistent event frequency (weekly, bi-weekly, or monthly).
  • A clear points conversion rule between event placement and season points.
  • A defined drop policy (what happens if a player misses an event).
  • Season-end playoffs or a champion declared from cumulative points.

MTG Super League's Series feature handles the cumulative standings automatically. Each event feeds into the overall series leaderboard without any manual tallying.

Organizer tip: Announce the full season schedule, event count, and scoring rules before the first event. Players will plan around it and commitment goes up significantly when they know what they're signing up for.

The Short Answer

If you're running a single-day cEDH open and want something with broad community adoption, Topdeck.gg is a solid choice.

If you're running a multi-week cEDH league or recurring series where standings persist, players have profiles, and the season tells a story, MTG Super League is built for that.

Eventlink, Challonge, and Start.gg aren't the right fit for either.

Frequently Asked Questions

No. Eventlink is built for sanctioned 1v1 WPN events. It doesn't support 4-player pods, custom scoring, or any of the key requirements for a cEDH event. You'd need a WPN account just to access it, and it still wouldn't do what you need.

Most competitive cEDH events do require deck lists submitted before round one starts. This makes the event feel official, reduces disputes about card legality mid-tournament, and gives organizers an audit trail for integrity issues.

For leagues, a placement-based system (4/2/1/0 or similar) tends to work well because it rewards consistent performance rather than just winning. For single-day opens, 5/1/0 is the most common and keeps winning clearly more valuable than survival.

The standard tiebreaker is OMW% (Opponent Match Win percentage) - the average win rate of all players you faced. If two players have the same point total, the one who played against stronger opponents ranks higher. Software like MTGSL and Topdeck calculate this automatically.

Yes. MTG Super League's Series feature links multiple events into a season with cumulative standings that update after each event. Players can track their season ranking between events. Define your points conversion rule (e.g., 1st = 10 season points, 2nd = 6, etc.) and the system handles the rest.
