Imagine this team composition
Heimerdinger, Caitlyn, Azir, and two other teammates. Everyone buys a Banner of Command (Cait could possibly not buy one) and a ZZRot portal. Siege mid. Take first tier tower.
Azir passive for where the turrent fell.
Place down 5 ZZrots somewhere where the enemy ADC can't easily attack them under your Azir tower (AKA right behind the tower).
Caitlyn places down all of her traps to prevent anyone from diving easily.
Heimer places down all of his turrents except ult turrent, saving it for a dive.
The next cannon minion wave, everyone uses their banner of commands on the minions.
Profit???
