The Altered TCG Official Tournament Guidelines are a guiding document to assist with the preparation, and execution of Altered tournaments. This document should be familiarized by players, tournament officials, and tournament organizers alike. It is the reference to follow for any Altered event held in an Organized Play setting.

Prior to the first World Championship Qualifiers kicking off next week, we're excited to share the updated tournament guidelines. We've thoroughly reworked this document with experienced community members to answer most questions from tournament organizers and judges.

This document will continue to evolve in the coming months. To help you keep track of changes, we've added an update tracker on the first page.

Players are not required to read and remember the Tournament Guidelines unless they are planning to attend an Altered tournament, in which case, they should be aware of the requirements detailed in the Player Responsabilities section.

While both the Comprehensive Rules and Tournament Guidelines are used in a tournament setting, the Comprehensive Rules are defined and should be enforced across all Altered events the same way. The Tournament Guidelines should assist organizers in executing events, and will provide a path for consistency, though it is impossible to proactively identify every situation a player or tournament official could find themselves in.

Altered tournaments are not a "one size fits all" experience, so we encourage using judgement and prior experience when working with this document.
