Rule 702.194c
Official source text from the 19 June 2026 Rules release
If part of a spell’s ability has its effect only if teamwork was used to cast it, and that part of the ability includes any targets, the spell’s controller chooses those targets only if teamwork was used to cast that spell. Otherwise, the spell is cast as if it did not have those targets. See rule 601.2c.
