I want to make a Protean Greninja that has Jolly as its nature, 252 SpA/ 252 Speed/ 4 HP, and is focused around its hidden ability Protean. I'm stumped as to what else I should include in its movepool:

-Shadow Sneak
-Water Shuriken/ Scald
-???
-???

I want to make this Greninja be prepared for any Pokemon my opponent sends out that would otherwise have type-advantage over Greninja.
