Arcanine:
Flame charge is not really good with Life Orb. The purpose you equip Life Orb is to increase the likelihood to increase the chance of OHKO.
Togekiss:
If you insist on Thunder Wave, get rid of your scarf. If not, get rid of Thunder Wave and spend all of your EV on Special Attack and Speed.
Milotic:
Why not utilize its ability MARVEL SCALE? I generally go with this:
- Scald (chance to burn, better than Surf.)
- Ice Beam (Type Coverage)
- Rest (Recover and increase your defense with ur ability)
- Sleep Talk (Troll while sleeping)
I think Flame Orb works too (like sumwum said), but I personally think Rest - Talking strategy guarantees longer and safer stall.
Ferrothorn:
Ferrothorn looks okay.
Haxorus:
Ok I understand you want ur Haxorus to have insane Attack Stats, but it is going to be murdered by 
or 
if you insist on Choice Band.
You should either equip Choice Scarf or Focus Sash if you want to Dragon Dance once before you start sweeping. Once Dragon Dance for Haxorus will allow him to outspeed almost everything.
BTW why not use Garchomp that is a perfect superior of Haxorus?
Sableye:
Same comment as sumwum. Will - O - Wisp pretty much cripples Attack Stat, so no need to spend EV on Defense.
Others:
Watch out for:
OHKOs Togekiss, as well as Milotic (not if Zapdos does not have something like Life Orb)
with Choice Band (counters Arcanite and Togekiss)
* 
You don't have to care about this kid UNLESS your team heavily relies on your Haxorus.
