i don't agree with hypnosis on gallade. the biggest mistake people make is thinking that gallade is fast/strong enough to be a starter, but his defense stat is so low, and considering the popularity of Choice Scarf starters, gallade won't have the opportunity to use hypnosis. heck, it won't even have the opportunity to utilize swords dance as a starter. my suggestion is that you go full physical on him and give it Choice Scarf.
i completely agree with alter ego on electivire. thunderbolt is important for foes like skarmory that have stronger defenses and because of Electivire's attack stat, will probably underestimate you by thinking you will use a physical attack on a physical wall. be careful for mirror coat.
leave 252 hp evs on it dusknoir but give about 144 def evs and put about 92 into sp def. that leaves 22 for attack. here's what i suggest for dusknoir's moveset: thunder punch/brick break/will-o-wisp/pain split. it NEEDS thunder punch and will-o-wisp. pain split is also a must because of its very low HP. brick break is preffered because it takes care of a lot of physical walls that will try to slowly kill dusknoir off.
i have a porygon-z myself, and its so awesome. here's what i suggest:
[email protected] Scarf
Modest/ Download
6 HP / 252 Spd / 252 SAtk
Dark Pulse
Tri Attack/Hyper Beam
Thunderbolt
Ice Beam
you wouldn't even need tri attack other than for its STAB. other wise, i experimented with it in battle, and hyper beam is excellent for a quick finish. modest is there for that lack of sp atk boost from nasty plot, considering scarf will take care of speed anyway.
