Is rooknight good?

Ok so I just got this arkadion from a gold egg, times it quite well, but I’m not sure if I should put it in my pvp team. Compared to my other egg only arks ( stegospike,charcalynx, subzy, mine spider) he seems a bit…off. Should I put it in my team?

He is quite useful if you know how to use him properly.

Ok thanks
