Also people, any tips about what I gonna to face against? What Pokemon he have use in your battles? Any info is important.

Honedge inclusion is obvious, but I'd bring Rose along too, since she'd generally be able to stuff all of Howl's Pokemon besides Spiritom with her Fighting STABs, and even then they have to deal with her Fire STABs. Third choice.....well, Heracross would be a good idea, since if he has Guts you can just Paralyze/Poison him before the battle to get that sweet + 2 STR, and his Bug STABs would be effective and devestatiing. Last choices I can think of for now (without a more thorough look through of your list of Pokemon) would be either Quetzoral or Honchrow, as the former is bulky and can stand to gain some more Happiness/Loyalty from a Gym Battle, while the crow would be able to resist all of Howl's Pokemom primary STABs and pester them with its own suit of Moves.

That's all the suggestions I have for now, so take them as you may!

Dark types, obviously.  Bug, Fighting, and Fairy type moves are your friends, depending on the exact matchups.

Howl also has a preference for canines in particular.  As evidenced by Nathan's battle, though, he has a few wild cards to pick from for particularly difficult battles.

3v3, battle til faint, no trainer items.

Thanks for the options guys! Lets see if my arrange of members party can be victorious against Howl. Lets see how things will go.

Doesn't D-Onix have ROCK SMASH now?  Or did you not factor that HM into the 'everyone has Fighting type moves'?  You are allowed to use HMs against Gym Leaders after all (just be mindful of who's around when you use ROCK SMASH in particular, of course.  Should be fine against Howl if the crowds are light since the gym leader knows we have it, though)
