Faries will be immune to outrage, meaning it won't get haxorus confused (I'm pretty sure?). It will be forced to switch out, but if haxorus wants to do anything it's got to make as much use of its base 147 attack as it can. Dragon Claw is simply just too weak.I'm not sure this is entirely my place to say anything, but should Outrage be replaced with something like Dragon Claw? Fairy types can be easily switched into Outrage, possibly confusing Haxorus (not quite sure on that)
Ah. Thanks for the clarification.Faries will be immune to outrage, meaning it won't get haxorus confused (I'm pretty sure?). It will be forced to switch out, but if haxorus wants to do anything it's got to make as much use of its base 147 attack as it can. Dragon Claw is simply just too weak.
An EV spread with max Speed and a Jolly Nature is an option here.
My apologies, but there's one more thing you need to do.
The main spread on both sets should be: 120 hp / 252 atk / 136 spe
The speed loss is largely inconsequential in the current metagame; you lose out on outrunning Lucario, which admittedly sucks, but it's worth the significant boost in bulk. You also beat the magic Speed number (263). And finally, Jolly nature + max speed needs to be mentioned in both sets as an alternative.
