The ones which I've been spamming are Gragas, Zilean, Zyra and Vayne.

Gragas just has an overpowering amount of CC with his Bodyslam, the stun has less than a 1 second downtime. Enemies can barely move nevermind fight back.

In the mode where anything can happen, Zilean is the ultimate protection against such antics. His ult is the ultimate protection against someone with the better URF pick against your team, and he can just constantly throw out a neverending stream of bombs. Stuns and Slows to keep enemies in lockdown.

Zyra is basically like an Azir who doesn't stop to attack. If her snare misses then her slowing plants are more than enough usually, and then she has her ult too. The entire field becomes overgrown with her plants given the correct skill combos, you still can only place two seeds down, however the amount of fully grown plants you can have is infinite (given the time limit on each plant).

And Vayne gets a 0.4 second cooldown on her Tumble.... and double bonus attack speed... nothing can catch her, nothing can outdamage her. As long as you're using your Tumble attack when you Tumble then there's no-one with better mobility. Also since Flash is on such a low cooldown you can easily position yourself for the perfect wallstun and it's pretty much over from there.
