How should i stat my Sword Strike?? :(

I need everyone's help here on how should i stat my Sword strike.. these are the 3 i am going for but not sure which 1 is better.

1) Full atk?
2) 3 spd oc atk?
3) 3 agi oc atk?

FULL ATTK!

i would either go hp def or since u want atk so much, hp atk.

but if u're limiting to one of the 3, full atk.

imo, hp would be good to get seed up before u dont have enough hp to rush someone

i've tried an all attack build and a HP + def build but personally i prefer the HP+def build as
it gives you a bit more survivability especially when you get hit by specs.

HP + def to get more out of seed mode and also bonus def for phase shift.
