Something kinda cool I thought of for Malzahar's rework.
What if every 10 or so units He kills with his E Malzahar gets to summon an extra voiding with his passive? Maybe enemy champions and large minions and monsters count as extra stacks? I feel that malzahar should be able to get more voidlings per summon later in the game. He is the prophet of the void and it's leader (as far as we know), so why not allow him to bring more recruits to fight for him? Maybe his E doesn't even need to kill it and it just needs to be applied on the unit when it dies to count. There are multiple ways this voidling army concept could work. As long as Malzahar's abilities are not gutted with all the damage being moved to the voidlings I think this could be a really fun idea.
