Rule 113.5
Official source text from the 14 November 2025 Rules release
Some activated abilities are loyalty abilities. Loyalty abilities follow special rules: A player may activate a loyalty ability of a permanent they control any time they have priority and the stack is empty during a main phase of their turn, but only if no player has previously activated a loyalty ability of that permanent that turn. See rule 606, “Loyalty Abilities.”
