Hello

I have been using Morgana for a bit now and was just wondering is there any other summoner like her?

Like her how?

Skillshot?

long root/bind?

AoE farming?

What exactly are you looking for? No 2 champions are identical, we will need some more info so we know what exactly you like about morgana and want on the new champion.

Morgana is not a summoner.

I wanted to troll but couldn't come up with anything.

Not really. She's quite unique. I guess Amumu somewhat resembles her.

Morgana is a champion.
You re the summoner.

Malzahar?

Her sister is kayle if you have an angel fetish.
Anivia is pretty close to her in terms of Skill shots and spells.

More serious reply:

Unlike some post-DotA MOBA games, champions in LoL are unique. They are not carbon copies of other LoL champions, or champions in other games.

For a similar play style though, you could try Anivia, Janna or even Sivir.
