Nothing. You can have it for free. And do you want a Skarmory/Charmander, I bred those like crazy and now I have too many>.>.
BTW, people, I'll trade any of the Pokemon I list for a Drill Pecking Impish Skarmory or a Stealth Rock TM. And I'll also give you like, 15 Pokemon's of the ones I've listed for a Bold Chansey/Blissey with good EV's (Or UT) with Aromatherapy/Heal bell and Seismic Toss.... :P
