I was thinking of trying Cho'gath support (normals)

I was thinking would be a good choice so i can use my passive and ult. Any advice on which ADC to pair up with? passive and ult make landing the knockup easier traps can combo with the knock up (root>knock up or knock up>root) net slow makes landing the knock up easier not really sure if they work well together not really too familiar with any possible combos here the attack speed boost Ez gives allies might help with Cho's E smokescreen makes landing the knock up easy chompers and zap = easymode rupture combos easier to eat people slow helps with rupture no idea slow for rupture. Rupture helps keep people in mf's ult blind + silence = no fighting back sivir's ult makes eating champs easier not sure slow for landing rupture and the other way around root into rupture, rupture into root stun knock up, knock up stun
