nihilego really hates steel and groud types, so magnezone comes in trapping the former with magnet pull and crippling the latter with toxic.
iron defense + body press preferred over specs for a better mu vs ferrothorn and melmetal, while speed for 252 azu, uninvested heatran and other id+bp zone that reach 191 for heatran. thunderbolt is the preferred stab due to higher base power.
leftovers is generally more useful, but chople berry let magnezone mess with some checks to nihilego like urshifu and kartana: if you remove those with chople berry, you nihilego will have an easier time doing its job. anyway, your job is to trap and remove steel types via magnet pull and either thunderbolt or id+bp, meanwhile you click toxic on the mandatory lando-t and ground types that will most likely want the smoke with either magnezone or nihilego: this way, nihilego's attacks coupled with toxic will wear those grounds down quicker, allowing both pokèmon to become even more threatening for the opposing team. with this set, magnezone also heavily pressures special walls that may try to stop nihilego, like blissey, with the only notable exception being av slowking-g.
