Azelf physical moves are : Zen headbutt, Return, Fire punch, Ice punch, Thunderpunch,Acrobatis,Payback,Iron tail and Explosion and he doesnt get sword dance ;P.
I've been using a sword dance bisharp and he doesnt cut it in OU. There is to much that outspeeds it , and pokes can use stuff like sub+attack(gengar) to avoid suckerpunch ( wich is common and its generally a good idea to sub first on bisharp to scout). I must say that i had decent succes with using bisharp as a psy/ghost/ killer. Pursuit and suckerpunch makes latias,latios,gengar,celebi and starmie cry.( used a special def/atk/hp spread that someone made up early b&w on smogon) But thats about all it does. Weavile does the same thing and better imo , and can also take on more pokes due to ice stab.
If you ask me we need to took into pokemon that used to be OU , and nowadays are not OU anymore because other pokes do their job better , but still have nice niches.This is because pokemon that were UU last gen and became UU this gen are there for a reason. They cant stand out against OU teams, and using gimmicky sets usually doesnt pay off. When om looking at smogon's OU list from gen3/4 to now and useage lists from when b&w was released, these pokes stand out : Metagross , azelf, dusknoir(dusclopsthisgen),flygon,hippodown,jolteon,kingdra,machamp,roserade,shymin,togekiss,weavile ,vaporeon,umbreon, darmanitan,snorlax,suicine,swampert,conkuldurr,whimsicott,eelektross.
Some pokemon of this list cant do a thing anymore this gen because everybody knows their sets back and forward , or they simply dont deal enough damage ( flygon , jolteon ,kingdra without rain, machamp still has a niche in dpunch but is outclassed by all the other strong fighters wich all have their niches,umbreon is quite useless in OU nowadays and hippodown is basically only used for sand.
Metagross is still quite the sweeper with proper teamsupport , and is able to take on terrakion 1on1 when they dont both dont have boosts( meteor mash).
Azelf is underestimated , has quick set-up, can run taunt to ruin walls.
Dusclops is a amazing wall that can wreck havoc but needs a good team to back it up.
Roserade is still a very good utility user with sleeppower/spikes/tspikes and carries a very handy grass stab to take out stuff like the common gastrodon.
Shymin is a decent pokemon,but doesnt get quite the coverage and good moves in for ou.
Weavile is still quite the good pokemon in ou , excelling at what it does ( killing ghosts and dragons.
Darmanitan is a powerhouse , but really NEEDs a rapid spinner for his flagship set with flare blitz.
Snorlax boasts great attack and can function as a special sponge ( thick fat,ghost immunity and having a lot of special attackers relay on focus miss to even 2ko or 3ko it is great)
Suicine is still a great defensive threat, tough a lot of BW OU pokemon can beat it 1on1.
With Swampert i get mixed feelings he seems decent but not quite good enough anymore ( every team packs a grass move anyways for gastrodon and quaggy or a other way to deal with those that can also deal with him)
Conkuldurrs useage is going down but he is still a very very good pokemon not to be underestimated.
Whimsicott is still a great team supporter but everybody will know how he works by now , making it very risky to use him.
