Are Pajantom and Miasmaw good CAPs?
I'm assuming this is SS CAP, and on the viability rankings / tier list, Pajantom is ranked at B+ because of its good Atk stat and access to Spirit Shackle for removing defensive Pokemon which sets its niche from a similar typed Dragapult, though the latter is a pretty bad physical attacker, it's still ranked S rank.
Miasmaw, on the other hand isn't even ranked, and that's probably because of the crippling Stealth Rock weakness and a much worse type combination.
