I got this Shiny Eevee with the Impish nature and these IVs: 31/31/21/x/20/25
It has non HA as well, and i was thinking if i should evolve it into leafeon. Would that be a good idea or would adamant leafeon be better?
Also, what evs for the Impish nature?
252 Hp/100 Attack/ 156 Def or
252 HP/252 Def/4 Attack
