Ruling Questions with Power Spray.

[Serperior]

OK. So the problem I'm having is this. When is it your opponent's turn so you can activate Power Spray? Here's a condition that bugs me.

Can I use Power Spray when I KO Dusknoir LV.X to prevent Ectoplasm?
Can I use Power Spray before Gengar SF uses Fainting Spell?

That's all, thank you.

You can't Power Spray either of those effects because when their powers go off, you are still in the "effects stage" of the knock outs, so it would still be your turn. Also, you know that the effects are only able to activate during your turn based on the text "during your opponent's turn."

I hope this helped!
