How Do You Beat Summoners?

Seems like the strat is to roll for 3 star Malzahar and then sit back and win the game. I have not found a comp capable of out DPSing how many voidlings he can spawn. Then you add Yorick and Annie and there are too many targets on the field which makes it impossible to kill their actual units. Azir nukes back lines for no apparent reason even with no items. But the main issue is Malzahar, he covers the entire field within seconds and its impossible to kill them faster than he can spawn them. At least that is how it seems to me, i have tried a few different comps but nothing seems to kill them fast enough before him and Yorick swarm the field. Even if you kill their units, their spawns deal damage to you so if they have only 1 unit left you take damage as if 3-4 units were left. Which late game means 20+ hp damage for barely losing.

Obviously there has to be a way of beating them that I am missing, I just can't figure it out.
