Rakan and Xayah V.S Kha'Zix (Lore Battle)

Based off lore, who do you think will win between these contestants? Will the Vastayan duo triumph through their usage of wild magic, or will they ultimately be consumed by the Voidreaver? I would say Kha has the advantage thanks to his ability to evolve and adapt, Rakan and Xayah probably would put up a good fight thanks to their innate magically abilities but eventually Kha'Zix will adapt and triumph over them. Thoughts?
