I like to run shark kisame, shisui edo deidara, and water main it's a pretty quick chakra build and lots of times, you can get off edo dei and shisui in the same round. Talents I run are 3, 2, 2, 3, 2 with king of hell summon. Although don't use it for space time. When this team is put on auto, it doesn't function well.

how about this one?

Shisui doesn't buff edo deidara. So there is no reason to have both of them in the same team.

Both of them have really strong teams, like the itachi-madara-shisui and the kisame-deidara-jimpachi, but 2 strong ninjas don't have to work well just because they are both meta.

The team can never be meta. Shisui does not keep deidara alive. If the remaining 3 ninjas are not helping deidara live or stack faster, it will not make a viable deidara team.
