Once overhyped, it is now overlooked.
I use CB Haxorus as a lead often. It is amazing. Not many pokemon like to switch into it. The ones that do are countered by magnezone so that's a few pokemon off the bat that you can KO.
Very overlooked. I've been playing around with my own CB Haxorus with a good amount of success.
Haxorus (M) @ Choice Band
Trait: Mold Breaker
EVs: 116 HP / 252 Atk / 88 Def / 52 SDef (Speed IV: 0)
Brave Nature (+Atk, -Spd)
- Outrage
- Dual Chop
- Earthquake
- Brick Break
If the Speed IV wasn't a dead giveaway, you're staring at a Trick Room Haxorus. While it's not as slow as most Trick Room sweepers, (179 Speed) Haxorus does hit far harder than his brother Druddigon and the two can actually pull off a 4th Gen Rayquaza-Salamence relationship but on a Trick Room team. While Dragonite's arguably better in Trick Room, Haxorus doesn't get OHKO'd by Pokemon in that low, low speed tier that carry Ice Beam and Haxorus just smacks them out of existence.
It works off two premises. One, that Haxorus is mainly countered by faster Dragons and doesn't have enough bulk to make great use of it's pure Dragon typing. (Which Trick Room & not running Speed EVs fixes) And two, in Trick Room, there's not a lot that can favorably take a CB Outrage & do much back to Haxorus.
Metagross, Bronzong, Ferrothorn, Forretress, & Skarmory are the only thing that really "stop & outspeed" Haxorus without getting a giant chunk of their HP axed off. And Metagross & Skarmory are the only one that can really do any damage to Haxorus since Gyro Ball only has 59 Power due to Haxorus' low speed. Ferro's Iron Barbs do more to Haxorus than it's Gyro Ball.
Point is Haxorus has an axe-face.
