MTG League Seasons: What They Are and Why You'd Run One
An MTG league season is a time-bounded scoreboard that runs inside your league. You set a start date and an end date, and every game played in that window contributes to a fresh set of standings — without disturbing your league's all-time or yearly ELO.
If you've ever wanted a "Spring 2026 cup" or a quarterly champion alongside the long-running ranking, that's what seasons are for.
What an MTG league season is
An MTG league season in Nerd Leagues is a named, dated period inside an existing league. The commissioner picks a title, optional description, start date, and end date, and the league gets its own season-specific ELO scoreboard for the duration.
Each season has:
- A title shown on the league page (e.g. Spring 2026, Q1 cEDH).
- A start and end date — games played inside that window count toward the season.
- Its own ELO standings for both players and decks, starting at 1000 and updating game by game.
- Its own ELO history, viewable in the league's ELO History tab when the season is selected.
Seasons live alongside the league's existing standings, not in place of them. Your league ELO and your yearly ELO keep updating as normal — a season just opens a third scoreboard that runs on its own clock.
Why you'd run a season
MTG league seasons make sense whenever you want a fresh competitive cadence without resetting the long-term picture. A few groups that benefit:
- Pod leagues with calendar rhythms. Spring, summer, fall, winter — each gets its own crowned champion. The all-time ladder still tracks the long arc.
- cEDH leagues running tournaments inside the league. A "Q1 Open" season can crown a tournament winner without distorting the ongoing rating.
- Groups whose all-time ELO has stratified. A season lets the bottom of the table start over at 1000 and get a real shot at the top — for a defined window.
- Multiple overlapping competitions. A monthly season and an annual season can run at the same time. A single game updates both.
The thing seasons get you is a second clock — a way to recognize recent results without losing the long-term record.
What changes for players when a season is active
When an MTG league season is active, three things happen on the league page automatically:
- A season pill appears in the league's tab row, next to All Time and any yearly tabs. Tap it to see Members, Decks, ELO History, and Games scoped to the season.
- Per-season ELO standings begin at 1000 for everyone the first time they play during the season. Wins, losses, and plus/minus track separately from the league's all-time numbers.
- Every league game played inside the season's date range auto-counts — players don't have to do anything different when recording. The season ELO updates the moment the game is logged.
Recording a game is identical to recording any other league game — pick the league, fill in players and decks, submit. If the game's date falls inside an active season, the season ELO moves on the spot.
What doesn't change
MTG league seasons are additive. Starting one (or three) doesn't roll back, freeze, or rewrite anything else.
- League all-time ELO keeps updating game by game. Nothing about your league's existing standings changes.
- Yearly ELO keeps doing its own thing — it partitions by calendar year, independent of seasons.
- Player and deck profiles still show your overall ELO and league-specific ELO. Season ELO is an extra view, not a replacement.
Archiving a season hides it from the league page, and a commissioner can unarchive any time. Deleting a season permanently removes its ELO data — pick archive if you're not sure.
Where to go next
Seasons are commissioner-controlled. If you run the league, the next step is creating one — the controls live under Manage League → Seasons. See The Commissioner Role for the full set of league-management powers.
