Rule 801.13
Official source text from the 19 November 2021 Rules release
Replacement and prevention effects watch for a particular event to happen and then completely or partially replace that event. The limited range of influence option can cause the modified event to contain instructions that can’t be carried out, in which case the player simply ignores the impossible instructions. See rule 614, “Replacement Effects,” and rule 615, “Prevention Effects.”
