Easy finds by chain fishing in Y, but impossible to get in X. Fortunately, I won't make you pay an arm and a leg for Skrelp. Have a junk shiny sitting in a PC? Have a 'mon with good nature and halfway decent IVs from trying to breed that perfect pokemon? Give an offer, and I'll take whichever strikes my fancy. Want a shiny Dragalge? Well, I already put some effort into it, and you'll need some seriously good bargaining skills if you want it.
