So champ pool decress due to nerfs

so original i was a big yasuo ,gnar, fizz, ahri , azhir , twisted fate, Katrina, player i mean by no means do i have a small champion pool but every time i start to like a champion i play them for like 3 or 4 days none stop to get good with them but the problem being now i have all these champions i was good with but they all have been nerfed sooooooooooooooooooooooooooooooooo hard like FIZZ............. that i relly dont have much i like playing and im scared to practice anyone else becase 2 days later they might get nerfed super hard as well so does anyone have and suggestion for me to try and play that hasent been fizzed nerfd i would love to know because i still have yet be able to get on a champion were i like them just as much as say like fizz or yasuo ..... so basically does anyone know who i should pick up thats close to any of these champs.......................... all of these tears are for fizz mains like myself who have lost ther favorite champion...
