Sorry If this is asking a bit much, but could you possibly RNG a Bagon to have Adamant, 31 IV Atk. and Speed, and shiny, I hear your good at it from your posts.
I can offer any 2-3 EV'd Pokemon of these... (If it's no trouble, could I get a clone back)
Regigigas (Lv.45) Adamant 252Atk/252Speed
Shiny Charizard (Lv.67)(Near perfect IVs) Modest 252Sp.Atk/252Speed
Groudon Lv.100 Careful 252Atk/252Def
