My reasoning with a Steelix *Is Kidding*If they happen to be cute then great, if not then it doesn't matter.
I notice how people say Smogon bases Pokemon off of usage... If that's true, why are some crap in the lower tiers being used in OU teams? Pratically every other team I see has a Gastrodon or a Quagsire, but they're still NU/RU. Cue confusion.
Anyways... If the favorites are usable if supported, then heck with it. My suggestion to any competitive battler, however, is when using Favorites, don't just slap them around :/ Be at least a decent player before trying funky things... Like Slaking or Regirock, for example. My Posted Threads if you be interested~
