6th Gen Greninja Competitive moveset & playstyle?

I'm training up my Protean Froakie which I bred(special thanks to the awesome user who traded me one), and I'm planning to use it for my rating mode battles. So, could you guys tell me...
1)a suitable moveset for Greninja that is easily obtained but still effective?
2)how to play Greninja using that moveset with Protean?
AsI have seen, Protean Greninjas are very versatile and can rotate between types easily, but I need a guide to help me along in playing Greninja properly. I(and all those like me) would really appreciate if you could teach how to use Protean Greninja to its fullest potential :) thanks!

Greninja's movepool is very good, but it suffers from 4-moveslot syndrome:
-Hydro Pump
-Ice Beam
-Hidden Power (Fire)/Dark Pulse
-U-turn
Nature: Hasty/Naive
EVs: 4 Atk/252 SAtk/252 Spe
Item: Life Orb
Ability: Protean

It can also set up quick Spikes to support the team:
-Spikes
-Hydro Pump
-U-turn/Hidden Power (Fire)
-Ice Beam/Hidden Power (Fire)
Nature: Hasty/Timid
EVs: 4 Atk/252 SAtk/252 Spe
Item: Focus Sash/Life Orb
Ability: Protean

Or it can go physical to catch the opponent off-guard:
-Waterfall/Water Shuriken
-Acrobatics
-Power-Up Punch
-Shadow Sneak/Night Slash/Water Shuriken
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Flying Gem
Ability: Protean
