If your are playing Dialga/Garchomp, the best possible way to play Power Sprays is about 2-3. Sure Power Spray can shine because as Dialga locks the bodies, Power Spray goes after powers, but here, Power Spray aren't really that greatly needed as Dialga/Garchomp decks are one of the decks that really don't need that many power sprays compared to decks like Luxchomp. Of course, that's what I'd think, as running 2-3 will most likely be how you'll be using it, but of course if you love power-locking, than you can go ahead and try out 4 if you'd like.:smile:
