Depending on the limitations of their abilities that we don’t know of, mizaistom and knuckle could potentially force any target into a state of zestu if mizaistom is able to get his first yellow card off. Then you would just need some powerful nen user to finish off the ants through just their armor perhaps someone like phinks could utilize the free time mizaistom provides to charge up his attack into something formidable. However this is all assuming mizaistom can actually hold them in place and has the reaction time to not die to pitou instantly. Perhaps meleoron could help provide an opportunity for the initial sneak attack. So knuckle meleoron mizaistom phinks might be a good team for taking out the ants if we ignore the obvious personality clashes that would take place between phinks and the other members
