Rule 614.10
Official source text from the 7 June 2024 Rules release
An effect that causes a player to skip an event, step, phase, or turn is a replacement effect. “Skip [something]” is the same as “Instead of doing [something], do nothing.” Once a step, phase, or turn has started, it can no longer be skipped—any skip effects will wait until the next occurrence.
