Top lane mains assemble!!! Help me find a champ

Ok, me and some friends have got a 5 man premade team we're climbing out of gold with and we need some minor help with our comp. Lemme give some backstory:

We've got an amazing ADC player that always pops of whenever he get his hands on , 2 supp mains including me and this other guy who's amazing at , a one trick and this other guy that went Garen top once and did 0 dmg in a 30 minute game.. Anyways, thats another story for another time... Our problem is that we lack serious cc and frontline pressure. Currently we have a set jungler and adc, however we usually swap top/mid/supp between the remaining 3 of us. Preferably we put the Thresh guy on supp since he'll make sure our adc get an early lead, and because we rely on our adc dmg we put the other guy in the mid lane (he usually plays , and ). This ends up with me top lane which isn't quite my prefered lane as a main, however this has left me with a bunch of game knowledge so we've decided that I'm most capable of peeling the backline. The problem is that I currently only play as well as in some rare cases. We need something cc heavy since the other guys' top lane champion pool consists of .

Ok this turned out a lot longer than expected but I'm looking for a cc heavy top lane champion that has a lot of front line pressure. Also I prefer playing enchanter supps/Bard and control mages so I despise anything related to the Riven/Fiora/Yasuo playstyle. Currently I've considered and, I'd genuinely appreciate any input from experienced top lane players with champ idea that kinda suits out teamcomp and my playstyle. Thanks in advance! [galio-happy]
