Blitzcrank + Kalista.
For those that don't know kalista can use her ult when blitzcrank is pulling somebody to basically carry the enemy further, then launch the blitzcrank back into the enemy, allowing him to knock them up, AGAIN, then use his ult for silence. Perma cc'd and carried a vast distance.
Is this balanced, summoners? (and no I didn't get destroyed by this, I just saw it in a game, I thought its kinda stupid).
And you can also use kalista ult if she has tp to carry somebody across the map.
Sorry no proof of these situations. You may do your own research.
