Why Canadian Highlander Needs Its Own Tools

Most deck-legality tools check one thing: is this card banned. Canadian Highlander needs a second check that almost nothing else supports - does this specific pile of cards add up to 10 points or less.

A deck with Black Lotus and Sol Ring is exactly at budget. Add Mystical Tutor and it's over by two, and that's not a banned-card problem, it's a sum. Generic tournament software has no idea it needs to run that math, which is how a deck plays three rounds illegally before anyone notices.

MTGSL treats Canadian Highlander as its own format rather than a reskinned Commander or Modern league: 100-card singleton with the printed exceptions, and the current points list checked and totalled on every decklist submission - every tier, every league. Pro Organiser leagues and up also get the deeper Scryfall-backed check against the shared Vintage banned list, the same tier boundary every other format on MTGSL already has.

How It Stacks Up

We looked. Nobody else does the points math for you.

Feature	Eventlink (WPN)	Challonge / Start.gg	Topdeck.gg	MTGSL
Runs Canadian Highlander at all	Not a WPN format	Yes	Yes	Yes
Checks the 10-point budget automatically	No	No	No	Yes
Singleton + 100-card minimum check	No	No	Manual	Yes, every tier
Vintage banned-list check	No	No	Manual	Yes, Pro+
Multi-week league + series standings	No	No	Event-focused	Yes
Free to start	WPN required	Free tier	Freemium	Free tier

Eventlink isn't listed as a gap by accident - Canadian Highlander doesn't appear on WPN's official format list, so there's no way to run it there at all. Everyone else can host the event; as far as we've found, nobody else checks the points total for you.

Built for the Format, Not Retrofitted

Points List Enforcement

Every submitted decklist is checked against the current points list, on every plan including free. Legal decks get a clear "X of 10 points used" confirmation. Over-budget decks are flagged with the exact cards and point values that pushed them over.

Vintage Banned List Checking Pro+

Canadian Highlander shares its banned list with Vintage. On Pro Organiser leagues and up, MTGSL checks every card against it automatically - no manual cross-referencing required. Free/Casual leagues still get the points-budget and construction checks above, just not this deeper lookup.

Singleton, Minimum 100

Construction rules match the real format: one copy of any card (with the usual printed exceptions), and a 100-card floor rather than Commander's exact 100. Extra basics never trip a false error.

Real Swiss Pairings

Canlander is 1v1, so it gets real Swiss pairing by record with OMW% and game-win-percentage tiebreakers - the same engine that runs Standard and Modern, not a multiplayer pod system bent into shape.

Moxfield / Archidekt Sync

Players link their Moxfield or Archidekt account once, then pick their list from their own public decks. Every re-sync re-runs the points check automatically as they tune the build.

Season Standings & Series

Run a single season or link multiple events into a series with cumulative standings. Head-to-head and game-win-percentage tiebreakers are calculated automatically, every week.

The Canlander community plays everywhere - MTGO, Discord-organized webcam matches, and in-person at LGS and community events. MTGSL works in all of them.

Canadian Highlander Software - FAQ

When a decklist is submitted, MTGSL matches every card against the current points list and totals up the cost. If the total is 10 or under, the deck is confirmed legal with the exact total shown. If it's over, the submission is flagged with a breakdown of which cards pushed it over budget and by how much.

No - unlike Commander's exact 100, Canadian Highlander only sets a 100-card minimum. MTGSL checks for at least 100 cards and singleton copies, so extra basic lands never trigger a false failure.

Canadian Highlander shares its banned list with Vintage rather than maintaining a separate one - the points list is what handles the format's own power balancing on top of it. MTGSL checks every submitted card against that shared banned list automatically on Pro Organiser leagues and up. Casual/free leagues still get the points-budget and singleton/construction checks either way, just not this deeper Scryfall-backed lookup - the same tier boundary as every other format's banned-card check on MTGSL.

Yes. Canadian Highlander is set up as a full league format in MTGSL: Swiss pairings, season standings, playoffs, and a Series feature for linking multiple events into one season leaderboard.

The free Casual tier supports one active league with core features including Swiss pairings, custom scoring, and the points-list check. Deeper decklist legality tooling and unlimited simultaneous events are part of the Pro Organiser tier.
