Rule 702.32g
Official source text from the 11 November 2016 Rules release
If part of a spell’s ability has its effect only if that spell was kicked, and that part of the ability includes any targets, the spell’s controller chooses those targets only if that spell was kicked. Otherwise, the spell is cast as if it did not have those targets. See rule 601.2c.
