He is not a ninja you should use. If you really want to use him (for cost of losing some games) use him with deidara.

is he really that bad<:3_41:>

Yes he is pretty bad. I advise against even touching him for anything other than transforming into him.

Just like boy kakashi and Konohamaru corps, they are just satire.

use them as sacrifice for orochimaru's edo tensei or buff them with Iruka's passive

maybe putting obito in the middle is a good idea i think? :L

Obito has very high life growth. I think it's highest of all my ninjas. I think biggest con of obito is his chase.
Try Hidan Obito Fire main Deidara. Obito mystery goes much better with deidara than 1st fire main (so you c*e 2nd or 3rd). Hidan gives hight combo so deidara active his chase. Team will have a lot of ignition effects.
It's just a concept, I try to use Obito when I up him to 3/4*. Its much more interesting to use him instead of meta teams.
