One Trick Ponies, what do you do when your champion gets nerfed/ receives a gameplay update?

Often times I overhear that one of the best ways to climb in ranked is to get really good at one or two champions, and just basically play them until your skill with that one or those two champs carries you in ranked. But, what do you do if those champions get nerfed? Especially for One Trick Ponies who play literally only one champ. Or if your champ gets a gameplay update, where even if they're better or the same in terms of power they're different and you have to relearn at least some of their kit.
