What tank should I get?

I play mages and adc. Syndra, Orianna, Ahri, Jhin, and Jinx are my best.

I am learning some top laners, and by far my favorite is Sion. I like how he's a front line champion, but has the immense team fight presence like mages have with aoe and cc, as well as how his abilities all have nuances to them. I like how he's a tank but there's something mage like about playing him, cuz he has range and heavily rewards good ability usage.

I'm wondering what tanks are similar.

Malphite is the obvious answer, but I feel he might be too simple. I'm not very fond of simple tanks like Illaoi and Yorick.

I am thinking Rumble, as he seems to perfectly fit what I like. Suggestions??
