29 pages? I skimmed several of them on my way here, so a thousand apologies if I've missed discussion of this kind of set.
I got interested in haxorus because my previous team used a pinsir as a physical sweeper because I dig his ability (Which is why I picked him over Heracross), and mono-bug typing is pretty rad (resists ground and fighting? Yes please!). Haxorus loses out on the bulk aspect a bit (Although it has higher HP) but gives him higher speed and monstrously better attack.

Coverage Move Here! (Earthquake/brick break/x-scissor, etc)
I had difficulty naming it. I was going to call it the Mayorus because the mayor of the town cuts the ribbon on the opening day of something, kind of like how he breaks focus sashes? Either that or depth charge because it destroys subs har har har.
I was looking through his movelist trying to see what kind of coverage I could get (Rock slide instead of stone edge? Bummer, but higher accuracy is okay, especially off that attack), and noticed something interesting.
Haxorus boasts the most powerful multi-hitting attack in the game. Double chop is only resisted by steel, and off his 147 attack is almost guaranteed to destroy a substitute, especially if he's had a chance to boost or something. It'll also help deal with pokemon that rely on focus sashes or sturdy to get free hits in. It has as much base power as dragon claw (80 plus STAB is both attacks hit), and off of his enormous attack that's acceptable.
Furthermore, with dragon tail, Haxorus can outspeed, damage, and knock away every OU defensive phaser that doesn't invest in speed (even Zapdos, with 100 base speed, is going to get sent out if Haxorus gets its speed up a bit), which gives it great staying power.
A boosting move is torn between swords dance to give it almost comical attack power, or dragon dance to make sure it outspeeds phasers and some of the common revenge killers (I think that it'd outspeed a non-scarfed starmie, and starmie are very very frightening).
The basic idea for this guy is to switch in on something that likes to put up subs to help set up (Breloom from last generation), or anything that likes to stall. Rather than taunting them to force a switch, Haxorus lets them continue setting up while he boosts once or twice (Depending on if they have to set up a sub AND leech seed AND something else, or if they're going to focus punch you right away), and then double chops to kill their sub and smash them. Things relying on focus sash, sturdy, or substitutes to take hits aren't going to fare well against the double chop, and it can use a fast, powerful dragon tail to knock away anything that tries to phase it out and deal with it later. The only real way to kill it is with ice-based priority or something that can outspeed it, and if they switch in something that Haxorus can take a hit off of, a second dragon dance would make outspeeding it -very- difficult.
My first item choice is the Shell Bell. If he's tearing into pokemon that like setting up huge substitutes, there's a chance he'll be dealing a lot of damage, and shell bell could reasonably outpace leftovers as recovery method.
Second choice is Yache berry, so you don't have to invest as many EV's in defence. Halving the damage of ice shard to 1x effectiveness is enough to keep haxorus alive and cause great damage to the weavile or mamoswine in charge (Which is why I think brick break might be a useful attack, as it will demolish weavile and really hurt mamoswine, as well as deal neutral damage to skarmory - earthquake will take out Bronzong).
If you're not worried about getting phased, you can change Dragon tail over for another attacking move for coverage.
I understand that this set misses out on a lot of his big draws (Such as the most powerful OU Outrage), but his incredible ability to take out substitute and focus sash users, as well as stay in against phasers seems like it could find a decent niche on a team.
Forgot! If you have any advice over moveset, EV spread, items, or especially set name, I'd be super happy!
