Stakataka - Stakataka is back but now on Rock instead of Steel. Just like on steel teams, Stakataka is virtually used the exact same way here, but it needs more team support in order to work and also has to be careful about the webs that the team uses, as it can compromise itself against other stakataka's or shuckle. Also like on steel, Stakataka works very well against offensive teams like dragon and sometimes electric. It can also choose to run a different item if another teammate like terrakion or omastar wants to use it instead, examples include Air Balloon and Life Orb.
Alolan Golem - One of the greatest additions to rock ever since its release and recent movepool buff in USM. Now that it has access to fire punch, it is able to trap and KO a lot more steel types like scizor and ferrothorn reliably thanks to its Magnet Pull ability. It's item also has some flexibility, as it can choose to run Fire-Z or Choice Band. Choice Band allows you to OHKO certain steels instantly (Celesteela, Ferrothorn, Scizor, Etc.) and let golem come in on more steels, while Z-move allows you to eliminate one steel type and use other moves freely so that you aren't choice locked. Overall, Golem has an easy role that allows it to succeed on most rock teams, and is almost always seen on one as well thanks to this role.
