KobaruonJolly- has access to swords dance to make up for lack of attack, Impish works too thanks to that excellent defence and steel typing, unfortunately lacks reliable recovery move.
Terakion[IMG]adamant or jolly- great attack stat and good speed
Birijion [IMG]Jolly- has nice speed, decent physical movepool, access to swords dance. Careful can work as well due to its high spdef.
Kyurem [IMG]Timid, but preferably hasty/naive since it has good offensive stats from both ends and that way you have access to its moves from both ends as its movepool is kind of shallow
