>>48687818somebody in pgg told me a long time ago that a 0 attack iv shadow mon has higher dps than a 15 attack iv regular mon. that really opened my eyes. certain shadow pokemon are only good for raids. in general, aim for a high attack iv, with reasonable def/hp.
for pvp, 0 attack 15 def/hp is best in most cases. except for ml of course where perfect ivs are best.
