Birdspam beats a seemingly competent (but not really) team, although not easily. Also, TIL Darkrai gets Swords Dance.
(L) Swords Dance! Finally, a Talonspam team that
isn't mindless Talonspam!
(L)...aaaand you're setting up on Primal Groudon, which can easily carry a Rock move. Max-SpA, sun-boosted, full-health Eruption gets the job done too.
(R) Groudon using Focus Blast against a team full of Flying-types. (And possibly at all--it smacks E-Killer on fully-special sets, maybe, but that's about it.)
(R) Hydro Pump Primal Kyogre when Origin Pulse exists.
(R) Two Kyogre, the second non-primal and also completely ineffective.
(R) SD/
Dark Pulse Darkrai. It gets Knock Off and Sucker Punch (also Drain Punch, Poison Jab, Rock Slide, and X-Scissor).
Come on.
(R) Say it with me now: DARK! IS! NOT! GHOST! Gengar also has Night Shade, which it doesn't need due to having an actual attack stat. Also, regular Ray+Mega Gengar>regular Gengar+Mega Ray.
