League of Legends (LoL) Question: is fizz good for low elo ?, i'm level 17

Hello!
Fizz is pretty good against unexperienced players as you roam can more around the map and snowball harder. Fizz is a fun champ (At least in my opinion) and is pretty easy to pick up. However, he has an extremely high skill ceiling and is hard to master. The champs you tried (Samira/Anivia) are very hard to play for a beginner. Fizz is probably an easier champ to help you learn the mid lane. PLaying Fizz is great at teaching you how to trade in lane and how to assassinate backline carries in teamfights. These skills can easily transfer over into harder champs like Zed and Qiyana. There are some pretty neat guides for Fizz here on Mobafire that you can read. r/FizzMains and the Fizz Mains discord are filled with super nice people who will happily answer any questions you have about the champ!

It's good to learn a champion like fizz early since your skills will come in handy once you want to play ranked, so I recommend playing him.

Fizz is the best option but if you want and you can play hard champions then play Akali , Katarina and Zed.
dont play Yasuo!!

FIzz is just broken, no matter how weak you are you will be able to oneshot someone with only your Q, he is pretty easy so you wont have a hard time learning him, there is definetly some skill expresion, like using your R while you Q so the enemy wont have time to react, also you will have to learn how to dodge abilities with your E, in general he is really easy and broken so yes, if you just want to climb play him, but he is usually banned,
