Does Encounter Power affect Pokemon that swoop down or come out of the bushes?

Question

I'm trying to encounter a Hydreigon on Victory Road and Pokemon only swoop down on occasion. So does Encounter Power help?

Answer 1

Yes it does, as it is considered a Wild Encounter, not so much just walking on Grass or Cave Floor.
