Rule 706.10e
Official source text from the 18 June 2021 Rules release
Some effects copy a spell or ability and specify a new target for the copy. If the spell or ability has more than one target, each of the copy’s targets must be that player or object. If that player or object isn’t a legal target for each instance of the word “target,” the copy isn’t created.
