My Next Mid Lane Champ Will Be...?

Wazzap! I’m a bronze 3 (sadly hardstuck) mid lane main. I play a lot of Taliyah (mostly), Lux (when I want to go simple yet one-shot) and Zyra (when I wanna go Lux but still not Lux-Lux). I also go Annie sometimes if I’m against an assasin. So, I got about 5500 BE, and I’ll keep saving until 6300. I’m so desperate after a new champipn cause I’m so bored of my current champs (exept Taliyah cause she’s hard to play = fun). The question is... who should I get? I really want Zoe cause she’s fun and can one-shot the shit out of carries. But I heard she got a nerf (and then a tiny buff) so maybe she’s not recommended? Or perhaps I should just go another mage fitting my ”playstyle”, for example Orianna, Malzahar. Or MAYBE (cause I’m bronze) I should just go Katarina or Fizz or Talon or Zed (not Leblanc tho cause I have her and she’s shit atm). But the thought of assasins... isn’t really appealing. I prefer either constant, AP damage dealers with control over fights (Taliyah!) or one-shot champs that are fun and preferably high rewarding (Zoe?). I’ve heard that Ahri (aside from all other assasins) is REALLY good right now for climbing, so maybe her instead (I also have a great skin shard for her, Star Guardian xD) And I’ve also heard I should get TF cause I play Taliyah, a 24/7 roamer. But Twisted Fate, compared to Taliyah, is really weak in teamfights, an important part of bronze games (everyone just goes run it down mid). So, who do you think I should get? (Take a closer look on my RANKED match history for more, please don’t judge my CS though, I’m working on it).
