Perfect Ev trained Speed Sp.Atk greninja Moveset?

Im trying to breed for a Perfect greninja,then EV train it.Any Idea what its moveset should be?

Majority of people say:
-Surf/Hydro Pump
-Dark Pulse
-Ice Beam
-Extrasensory/U-turn

A lot of people say U-turn is best for the 4th move but I really like Extrasensory since that makes Greninja an excellent check to mega venusaur

Personally, I play doubles VGC and My Greninja is a beastly sweeper with life orb. I run:
-Mat Block (Not useful for singles)
-Dark Pulse
-Extrasensory
-Grass Knot

He has great coverage and a pretty unexpected moveset. I use him primarily to set up another pokemon, but after that first turn, he does some serious damage. Very reliable pokemon.

I have
-Toxic spikes (Egg Move)
-Ice Beam
-Dark Pulse
-Grass Knot
It has great coverage plus great entry hazard support with the Toxic Spikes stopping switch ins and crippling immediately.
This set works for me in singles and doubles, I don't triple battle often.
Like coachory I also use a Life Orb on Greninja
