Might I ask what the IVs are on the Timid Azelf? Also just outta curiosity the Modest Shiny Mewtwo?
I know you're looking for a Froslass which I don't have but I do have a
Modest Snorunt with these IVs. 31 / 29 / 27 / 31 / 12 / 31
Its level one and untouched and I bred it myself. :)
Also if you have any pokes with good natures and IVs I'd be interested in those instead.
