Can Evee yous a moon stone and a ice stone?

Eevee cannot use both a Moon Stone and an Ice Stone; it can only evolve using one stone at a time based on the desired evolution. A Moon Stone will evolve Eevee into Espeon or Umbreon (depending on the time of day and friendship), while an Ice Stone will evolve it into Glaceon. Players must choose the appropriate stone based on which evolution they want for their Eevee.
