From what I remember, Haxorus has a pretty good movepool. If you had a Haxorus (maybe you have one in the games?) what moves would it have?
Draco Meteor, Dual Chop, And Dragon Rage.
Dragon Dance Outrage Earthquake Aqua Tail/Night Slash/Poison Jab/X-Scissor/Substitute
For Haxorus pretty much any high critical hit ratio move but its speed can be a problem. Have it keep Dragon Dance and Dragon claw or Dual Chop. It comes in handy My Haxorus is at lv 94 and can tear through the entire elite 4 in Pokémon White with using Dragon Dance 3 times. I sometimes have to re-heal him but its worth it! Its moves are Dragon Claw, Dragon Dance, Earthquake, and Brick Break for those pesky Ice Types.
