Decidueye in Emerald Imperium

Grass / Ghost — where to catch it, what it learns, and how it differs from the official games.

Compared with the official games

Stats Sp. Atk 100 → 95, Sp. Def 100 → 85, Speed 70 → 100 (total 530 → 540)
Abilities gains Tinted Lens and loses Long Reach

Compared against present-day official data. The Fairy type and hidden abilities arrived after Pokémon Emerald, so a difference here can belong to the series rather than to this hack.
