Swiss structure, tiebreakers, deck checks, time extensions, and appeals in practice.

Swiss and the cut
Most Competitive events use Swiss pairings: players with similar records are paired each round, nobody is eliminated during Swiss, and the number of rounds scales with attendance. After Swiss, the top players (commonly a Top 8) advance to a single-elimination playoff. The number of Swiss rounds is determined by player count so that the standings are meaningful before the cut.
Tiebreakers
Standings are ordered by match points, then by tiebreakers, in this priority:
- Opponents' Match-Win Percentage (OMW / OWP) — how strong your opponents were.
- Game-Win Percentage (GWP) — your own game win rate.
- Opponents' Game-Win Percentage (OGW).
Each opponent's win percentage has a minimum floor of 33% so that a player is not overly penalized for facing someone who did poorly. Byes and drops are handled by defined rules in the MTR.
Deck checks & time extensions
Deck checks verify a deck matches its list. A mid-round check must not cost the players game time — the time used is added back as a time extension. Any judge call that consumes match time (rulings, deck checks, slow play investigations) should be compensated with a time extension so neither player is disadvantaged.
Appeals in practice
When a player appeals, the floor judge gives the Head Judge a concise, neutral summary of the facts and their ruling, then steps back. The HJ makes the final call. A healthy team treats appeals as normal and as a learning opportunity — being overturned is feedback, not failure.
