>>44015076Everyone just says steel fairy because its just the mathematical answer, but only for the defensive aspect. Also, resisting things like bug is not as valuable as resisting something like ground so you shouldnt rely on the mathematical thing way too much.
Some types that are good both offensively and defensively:
>Dark/Poison>Normal/Ghost>Fighting/Ghost>Ground/Flying>Steel/Ghost>Steel/Fighting>Inb4 zamazenta bad and zacian goodZamazenta has just way worst stats, is a defensive pokemon forced to lower its defense when attacking, loses speed when crowned for some reason, and has a way worse ability, if zacian was steel fighting it would be definately be stronger than steel/fairy zacian.
