Used to use them a lot and have some tips.
1.Zody will be a much better leader for clones than rex .
2.you are going to need 200 speed min on Cody as getting out his 501st special is what makes the team.
3. Try to get as much crit chance on all clones . Mod 4 crit dam 2 crit chance on Cody, sergeant.
4. Use a good offence set with offence secondaries for echo as he will assist tons.
5. Mod fives for tenacity , potency and tankness.
6. Rex mod however if I use him as 5th (ZPrincess Leia or Zarris work very well with the team )
