Avalugg's biggest weakness is its poor Special Defense, but Articuno can patch that right up. It also helps relieve Avalugg of its spinning duties if need be, which comes in handy against Ghost or if they have a spinblocker. Articuno could also help check Fighting-types and bulky setup mons, like Keldeo or Clefable (with haze). Articuno isn't as pressured to beat opposing hazard setters since Avalugg can also spin them out, so it can be used more effectively too.
