Digital events governed by this document are run using the Magic: The Gathering Arena (MTG Arena) Game Client.

There are currently two major Types of digital events: Online and LAN. In Online events, players are generally playing from remote locations using their own device and connection to play. In LAN events, players are generally playing in the same place using the same network connection.

Sanctioned tournaments, including both tabletop and digital events, are divided into two types: Premier and non-Premier. Premier tournaments are run by Wizards of the Coast or select Tournament Organizers. They have unique names and features. Non-Premier tournaments include all tournaments that are not explicitly Premier.

Some Premier tournaments may consist of both Online and LAN stages within the same tournament.

There are two major tournament formats: Limited and Constructed. Each tournament format has rules specific to its format. In Limited tournaments, all product for play is provided during the tournament. In Constructed tournaments, players compete using decks prepared beforehand. Some Premier tournaments may consist of multiple formats and stages within the same tournament.
