You aren't really approaching CB the right way. The question isn't "here is my team, what can make it better". The question should be "what kind of teams can I build around the champs I have". I suggest you consult https://deadwoodjedi.com/

With that in mind - from the champs you do have, the specific team you want to build towards is eventually going to be one built around Demytha: https://deadwoodjedi.com/speed-tunes/myth-heir-salad/ - but you're missing Seeker. Specifically, if you look at https://deadwoodjedi.info/cb/9c4ed804955fc99ac9334bc119fbc502ed53b680 you'll see that you literally are just missing Seeker, since that comp even uses Draco. There *may* be a way to make that team work with Deacon instead, but it's probably not worth the effort, as you'll need absurd speeds to compensate for the lower TM boost.

In the interim, I think I'd probably just go with an untuned team built around Draco, Salad, Doompriest, Nazana, and Demytha. It's not really ideal, especially untuned, but between Salad and Demy, you should be able to cycle turns enough to get some reasonable damage.
