Stealthrock + mimikyu decoy?

Question

So I am currently S.O.S chaining a shiny mimikyu and I'm curious. Would moves like stealth rock be able to destroy the decoy so I would be able to one shot it?
Do Pokemon called for help even get effected by that?
If not, any other effective way of destroying the decoy without wasting a turn?

Answer 1

I use a Mimikyu competitively and can say with confidence that Stealth Rock does not brake Disguise. Sorry to say, but you will have to waste an additional turn.

Answer 2

Any indirect damage, such as entry hazards or status moves will not break disguise.

If not, any other effective way of destroying the decoy without wasting a turn?
