Which Element Canna Is Worth it?
Simple answer: Wood for Clan Titan & possibility Dark for diversity
Honestly, none of the Canna is really worth it. The only one even worth considering is the Wood Element and possibility Dark if you honestly don’t have anything better.

Is It Worth Rebirthing for Canna?
If you have Natural 4 Astromons to burn away, then by all means do it for the Astrogems and for collection. Or if you are an Clan Titan player, do it for the Wood Element, although it does not even come close to a Wood Merlin at all.
The biggest reason for anyone to rebirth Canna would simply be an exchange of 30 Natural 4 Astromons for 600 Astrogems. Then an additional sacrifice of 15 Nat4s to reset and repeat the process.
Reason two would be simply to finish your collection, not only would it look pretty having it all collected, but you get Astrogems for doing it too.
Reason three would be if they need some filler Wood CS Astromon for Clan Titan
Reason four would be if if they need some dark nukers since they haven’t gotten any strong ones yet such as Dark Mona.
Will Fayie Build Canna?
I have a Wood Canna that I gotten in the past, I threw a few random gems on it and called it a day. It isn’t strong by any means nor is it really useful. I didn’t really care about it back then and I still don’t care about her now. Which shows how useful she really is even in the content she excels in. Only reason why I would consider rebirthing for her is to finish off my collection.
