Tapu Koko+Alolan Raichu combo

[DanielJames]

So now that I've been breeding competitive Pokémon over the past week, I want to start putting together a VGC team. One of the possible combinations I have access to is Tapu Koko and Raichu. The sets I'm running for are these:

Tapu Koko @ Life Orb
Naive nature
252 SpAtk/252 Spd/4 Atk
-Wild Charge
-Volt Switch
-Dazzling Gleam
-Protect

My issue is that I don't have a Timid nature one. The one I caught is Naive so that's all I have to work with right now. Wild Charge hits hard and can take down special walls easier, Volt Switch for positioning, Dazzling Gleam for STAB and spread damage.

Raichu @ Focus Sash
Timid nature
252 SpAtk/252 Spd/4 HP
-Fake Out
-Electric Terrian
-Thunderbolt
-Speed Swap/Psychic

Fake Out support, Electric Terrian gives me another option if Tapu Koko goes down, and the other two are STAB attacks. I kind of want to run Speed Swap though so I can bring in a slower Pokémon and give it ridiculous speed. Not sure what to run at the moment

I just need some feedback on the sets and also some good Pokémon to pair these two with!
