Ominous Wind - Moltres, Suicune, Salamence, Yanmega, Ninetales, Togekiss, Altaria, Vespiquen
Out of them, Togekiss is the only significant addition, since Serene Grace raising Ominious Wind's secondary effect to 20%. Still, it already learned Shadow Ball for a stronger Ghost attack, and already had Ancientpower for Ominous Wind's secondary effect (of which it had no stronger Rock move substitute).
Meh, without Serene Grace, its 40 Base Power really is not worth it for such a meh typing.
Air Cutter - Articuno, Zapdos, Drifblim, Altaria, Honchkrow, Yanmega, Vespiquen, Xatu, Mantine, Pelipper
Meh move, no comment.
Signal Beam - Articuno, Cresselia, Regice, Magnezone, Glaceon, Espeon, Jolteon, Vaporeon, Hypno, Electrode, Manectric, Togekiss, Electivire, Starmie, Slowking, Alakazam, Slowbro, Froslass, Raichu, Jynx, Empoleon, Luxray, Bronzong, Claydol, Mr. Mime, Blastoise, Wormadam
A move with okay BP and a good typing, should be a good addition to a lot of those Pokemon's movepools, several of which will really benefit for having very shallow movepools a (Jolteon, Magnezone, Cresselia, etc.).
As it's been said before, No Weaknesses FTW! Platinum's being very kind of Luxray so far, with Signal Beam, Magnet Rise, and Superpower.
Earth Power - Regigigas, Whiscash, Quagsire, Swampert, Garchomp
The Three Water/Grounds can make good use of this move, but Earthquake is probably better either way.
Iron Head - Raikou, Entei, Suicune, Kingdra, Probopass, Magnezone, Mamoswine, Bronzong, Miltank
All pretty meh. Raikou might be able to use it for the Speed Advantage, but Bronzong's Gyro Ball will almost always be stronger anyway, and Mags and Probo can't really viably use Physical attacks anyway.
Icy Wind - Suicune, Drifblim, Mismagius, Tentacruel, Whiscash, Blastoise, Octillery
Meh move for standards. Suicune might better function as an SD Yache Chomp counter with it, though, with the first hit lowering SD Chomp's Speed and taking its Yache Berry away, and the second hit allowing it to outspeed Chomp and Ice Beam for the KO (i've done the calculations: 0 Special Attack EV Suicune vs. 4 Special Defense Garchomp w/ Yache. Icy Wind through Yache Berry would do at least 23% damage, and the Ice Beam after it would do at least 81%. Maybe Blastoise can to, though it already knew Icy Wind didn't it?).
Outrage - Salamence, Flygon, Nidoking, Kingdra, Snorlax, Gyarados, Lapras, Rhydon, Tauros, Marowak, Venusaur
Salamence being the obvious best receiver of this move. Dragonite's almost obsolete now thanks to that. Now it's going to be even harder to switch into Salamence. Flygon would still like Dragon Dance, though. Nidoking can also now pull off an Earthquake/Outrage/Fire Blast/Filler set. Snorlax and Gyarados can also make okay use of the move.
Superpower - Dragonite, Flareon, Rampardos, Absol, Blaziken, Tyranitar, Snorlax, Mamoswine, Hippowdon, Luxray, Ursaring, Pinsir, Armaldo, Honchkrow, Donphan, Golem
....... okay, better question, which of these Pokemon do NOT benefit significantly from getting Superpower?
Seed Bomb - Donphan, Cradily, Shiftry, Snorlax, Ambipom, Vileplume, Victreebel, Carnivine, Jumpluff
Interesting move to say the least, Grass is an okay attacking type, and a good addition to many of these Pokemon's movepools. Cradily and Shiftry can obviously make good use of it due to STAB, and Donphan might be able to make good use of this move since it would hit Grounds, Rocks, and Waters harder than Earthquake (and of course, hi2u Swampert).
Heat Wave - Zapdos, Togekiss, Crobat
Zapdos gets a welcome addition to its tiny movepool. Togekiss, meanwhile, already had Flamethrower which had the exact same burn chance.
Dive - Politoed, Lanturn, Quagsire, Cloyster
Ludicolo wants Dive back dammit. It's probably the only Pokemon that can make the most use out of the move. So it had better get it by the time the game is released.
Trick - Porygon-Z, Drifblim
Always a welcome move, though neither of those can make very good use of it.
Zen Headbutt - Bronzong, Claydol, Lapras, Blastoise
Bronzong seems to be the only one that can make good use of it because of STAB, and none of them can really utilize its flinching effect.
Gunk Shot - Toxicroak, Slaking, Snorlax, Ambipom, Donphan, Infernape
Lol, Poison.
ThunderPunch - Ambipom, Rampardos, Lucario, Toxicroak, Flygon, Probopass
Once again, most of those Pokes benefit greatly from getting a good physical Electric move. Lucario especially, now Gyarados wont be able to safely switch into it.
Fire Punch - Ambipom, Rampardos, Probopass
Ambipom likes any addition to its movepool. It doesn't get a Technitian boost from it, sadly. There had better be more guys that get it..
Ice Punch - Ambipom, Lucario, Toxicroak, Floatzel, Probopass
Well shit, there goes Gliscor as a 100% physical Lucario counter. Toxiccroak and Ambipom again like getting any addition to their physical movepools, and Floatzel wont just have to stick with Ice Fang.
Sucker Punch - Shiftry, Froslass, Golem, Skuntank
Shiftry gets a huge boost thanks to STAB on this priority move. Skuntank also gets STAB, but Skuntank fails at life.
Aqua Tail - Lapras, Walrein, Drapion, Seviper, Gligar, Quagsire, Salamence, Swampert, Slowbro, Slowking, Armaldo, Rhyperior, Golduck, Tyranitar, Garchomp, Floatzel
Meh, Waterfall is probably a bit better on those who learn it. Though some of those that don't learn it welcome having a physical water move they can use.
Meh.
Knock Off - Toxicroak, Ambipom, Empoleon
Good move, Empoleon would probably make the best use of it.
