Ok...
1. This is VGC, there's item clause. So...
Politoed: Leftovers -> Damp Rock
Goodra: Life Orb -> Sitrus Berry or Anti-Dragon Berry (whatever its name is)
2. Ludicolo: Synthesis -> Protect. Synthesis is garbage in the rain.

---

Item clause means you cant have 2 of the same item. 1 item per team is allowed.
Use protect over synthesis on ludicilo
Hp Ice over volt switch on manectric.

---

Dont't use flamethrower on manectric. its power will get lowered by rain. use some other type of attack.

EDITS:
Politoed now had Damp Rock instead of Leftovers
Ludicolo has Giga Drain instead of Synthesis
Goodra has Roseli Berry instead of Life Orb
Manectric has Hidden Power instead of Volt Switch, and Toxic instead if Flamethrower.
