come to think of it. For the 5 IV vivillon with Savanna pattern. I have a few pokemon that might interrest you.:
-Umbreon Shiny with perfect deffence stats
-Glaceon Shiny
-Milotic Shiny
-Larvesta Shiny
-Absol Shiny with perfect speed
-Gible shiny with perfect atk, def and sp.def
-Hawlucha 5IV
-Fennekin 5IV
Choose amoung those, don't fear to take a shiny, i lost my interest in theme since it doesn't make them stronger. (Except for my new umbreon because he's a 5IV)
