Darkrai Lv.X & Dark Gengar coin flip.

[rerobey]

Dear Masters,
My opponent hits my active pokemon with their Darkrai Lv.X "Endless Darknes" and they also have
a benched (Neo Destiny) Dark Gengar with the "Deep Sleep" poke-power.
Questions:
How many coin flips?

What is the order in which to deal with this arrangement?

Thanks again.........Rich

As an ongoing effect, Deep Sleep overrides the onetime application of the attack's effect.
Deep Sleep would control the result.
