Best mid lane mage?

I'll just give you an overview of the champions depending upon the division first:

Platinum+ Aurilion Sol
Platinum Zed
Gold+/- Zilean

However, you don't have to start mastering the champion which is listed above just because they're OP for now. Go for the champs you're comfortable and have sustainability.

I'll enlist the champions which in my opinion, may help you in lane:

Ahri (good escape plus burst late)
Lux (long ranged spells, CC and OS)
Annie (easy farming even if you're behind and can turn the tables late game with flash+ult combo)
Zoe (heavy burst and OS but difficult to master)

Hope you can do well, good luck!

Velkoz is strong rn like leBlanc and ryze just try what u good with and the champs good

I main orianna, that's the only champ I play and I got diamond 3 by doing that, for 3 consecutive seasons. Just learn a champ real real good and you're fine, go for someone you find interesting, I went for orianna since her skill cap is really high.

I always play lux or wukong mid.

Both are strong but i like lux more because of her op range.

heim is fun and is good for map awareness training same for positioning

Nothing better than giving aids to people as Zoe or Kat

Aurelion is the best if you know how to play it ! 53% wr for 1,5% pickrate lol

Lux is a nice pick if you're looking to poke but Galio has always been one of my favorites for the sustain

100% the best is malzahar. super op in mid lane & best in clashing
