Question about Claire voyant synergy

Baseballplyr

My question is about Claire Voyant's synergy called fire and forget, where if the opponent is immune to incenerate they are instead inflicted with a slow debuff decreasing evade and unstoppable by 100%. What is the purpose of this synergy, I can't think of any champions who this would apply to, meaning an evade champion who's immune to incinerate. Can anybody give input on this.

Only applies naturally to Annihilus I think.
