Mega Alakazam loses Trace and gains Pure Power.>Primals are unaffected. So is Arceus. Bulbasaur family: Dry Skin
Mega Venusaur: Aroma Veil
Pikachu family: Victory Star
Eevee: Protean
Espeon: Tinted Lens
Umbreon: Filter
Vaporeon: Dry Skin
Jolteon: Iron Barbs
Flareon: Fur Coat
Leafeon: Natural Cure
Glaceon: Refrigerate
Sylveon: Serene Grace
