Rule 610.4a
Official source text from the 7 August 2020 Rules release
A permanent phased out this way doesn’t phase in as a result of the turn-based action during a player’s untap step (see rule 502.1). Other effects may cause it to phase in. If a permanent phased out this way phases in due to another effect, the second one-shot effect doesn’t happen, even if that permanent has phased out again.
