Rule 720.1c
Official source text from the 13 July 2018 Rules release
Tournaments use a modified version of the rules governing shortcuts and loops. These rules are covered in the Magic: The Gathering Tournament Rules (found at WPN.Wizards.com/en/resources/rules-documents). Whenever the Tournament Rules contradict these rules during a tournament, the Tournament Rules take precedence.
