Hybrid Malz is the way to go, pure AD malz is too sqhishy and too reliant on voidlings to be safe.

That means the moment they realize how much damage voidlings do, they'll quickly take them down, and before you can make another they'll throw everything at you, knowing you don't have escapes or high MS (and if you do have MS from PD for example, that means your voidlings are weak since they only benefit from AD/ArmPen).
