I will be clear, I think this pokes needs a rebalance and I consider these changes would be fine for it:
Haxorus
Passive (new): Dual Chop
Dragon Claw > Crunch (15seg)
Deafen
Dragon Rage > Poison Jab
Low Kick
Surf
Dragon Pulse
Dual Chop > Assurance
False Swipe
Draco Pulse > Shadow Claws
Dragon Storm
First of all, we know that a good dragon poke is the one that have more moves from another type than the dragon ones.
These changes would give him variety in pvp side, in this way with the dark and ghost moves would be usefull using it against ghost pokes which are more used in pvp nowadays.
Also, I consider the Bubble blast formule is good although sometimes fails, but I want to emphasize this formula isn't good with dragon dmg(Dual Chop), I mean the only objective of this move is to deal good dmg against other dragons because if u use it against other poke it will deal too little dmg, for this reason I consider it useless.
Then, Adding Poison Jab would give him an opportunity against fairy pokes.
