Fast E
- When ur fighting close to wall you can use E to bait enemy's dash ability or flash by just e'ing through the wall and coming back with second E
- Before you use it make sure you hit it (It's realy easy to miss it xD)
- When you want to hit fast E on someone who in aa range should use it on left/right instead of forward
- Never use fast E for waveclear

Slow E
- Good for gank setups because of slow ( 40% / 45 %/ 50 %/ 55% / 60%)
- It's almost impossible to miss
- It has 2 times more range than fast E
- Never use slow E when your slowed

NOTE: You don't have to stick to one plan, always try to adjust it up to the current game stage. Be creative, and don't be scared of testing. People learn the most from their mistakes GL

Level 1
Most likely you're going to start with E and use it to last hit 1st, 3 melee minions and try to not push. If you are against melee champion with weak level 1 you can start W and try to trade

Level 2
Try to last hit with W, don't let wave crush under the turret and not take too much damage. In some meetups you can try to trade (e auto w) only if you are 100% sure you will win

Level 3
Now you can start trading with q auto w and keep me to get out or try to hit it on the edge. When cannon wave comes try to push and follow potential river fights

Level 6
Try to all in with R and ignite you should most likely kill the enemy if not its fine u forced his recall push wave and reset, if he didn't back try to dive him

Level 7-Mid game
Try to roam a lot its the best way to snowball games as fizz. Before you do it make sure your wave is fine and you don't lose too many minions cuz if you fail roam u gonna make a game harder for yourself. If you roam worked you should help push wave and crush it under turret (you can stay for plates if you want)

Midgame
Dont perma siege go sidelane If your team didn't take tier 1 turret you can try to take it, if its taken and you see enemy team you can try to crash it under tier 2 turret, if your team started teamfight without you, look for good flank and one-shot their carries (if you are not fed enough peel for your adc) if the game isn't fiesta most likely someone will try to catch pushed waves. You should try to solo kill him and force 4v5 fight

someday i will do it ;/
