If I'm good with these champions what are some other ones I'd be good at?
Nid, karthus, soraka, wukong, shyvanna,teemo, malphite, and nasus
Nid, karthus, soraka, wukong, shyvanna,teemo, malphite, and nasus
Poke based champion. Any champ that can poke for lots of damage and get close for the kill. I would say:
Zoning Champion. Hes made for dealing constant dmg to champions while farming. Benefits the most from spell casting for max effectiveness. Ex.
. Healer and CC, Teamfight efficient. Ex.
Their kits are basically disrupting teamfights. Choose best for different Champs.
Standard initiation Fighter. Made for taking hits and dishing them out. Good at any stage of the game, but works best when fully itemized.

Tanks, and not just tanks, but Monsters on the battlefield. Their kits are made for the specific purpose of Dealing all their damage while you tickle their life. But they all have a drawback that they are TIME dependent. whether its stacking, farming, or itemizing, they dont give out their full battle power early game.
Ummm i cant think of anything that compares to satan (teemo). But his kit single target ambush and damage over time. champs that are like that are:
This guy falls under the same category as Shyvanna. So there is no need to repeat it :)
This guy falls under the Wukong category, but leaning heavily intho the Shyvanna one.
I wrote a lot, but it all depends on your playstyle. I wrote it like this based on my experiences and how i managed to play them. there may be changes and there are missing champs, but the missing ones actually dont fall under any of the mentioned playstyles (in my opinion, i could be wrong) HOPE IT HELPS.
Nid- Any poke based champion, Jayce is similar because you land a Q then all in them.
Other than that the rest are fairly unique. Maybe Karthus/Anivia. Mana stack and zone control
seems like you go TOP and support... ?
- Starts with her Ultimate. Another champion who starts with an ultimate who can also go a good full AP top 
Global ults.. heal and damage. perhaps maybe
?
Like
? maybe you're like tristana and may also like 
AD melee top laners.... 
Stacks.... 
So my thoughts... you MAY like..

Teemo, Malph and Nasus are all strong against AA-reliant champions (more Teemo and Malph, but Nasus's AS slow is still pretty noticeable). I'd recommend trying Jax. He may not be as good in the current meta, but he still duels incredibly well. His playstyle is a little bit like Shyv, but you trade teamfight potential for splitpushing, and you also scale into one of the strongest late-game duelists in the entire game.
