Angel is really good if you can get her, pair her with shark kisame for chakra and start ripping through jin and gnw. Edo deidara is also great, though lack of jinpachi from what i can see means he wouln't have a consistent source of double attacks, other wise kisame and edo sasori are good pairs. Shisui is good as a strong barrier nin that can be used for future uchiha teams or lightning/fire blitz and has the perk of being the relatively cheapest of the 3 ninja. It based mainly on what you like running, though angel is huge if stacked for any team based event, i should know cleating lvl 80+ jin event in around 3 minutes with a single partner.

Ay works well with fellow cloud units or heal team to keep him hp up. Shisui works well with fellow uchiha members, with a decent team being iruka anbu itachi shisui and lightning main.
