Important Mechanical Changes:
- Red Orb and Blue Orb can be used as Mega Stones and grant Pokemon with the relevant boosts.
- Aggronite now grants a secondary Steel-typing, rather than removing secondary typing.
- Pokemon who are banned from Mega Evolving may still Mega Evolve with a native Mega Stone (Mewtwo-Mega-Y, etc)
- Pokemon can evolve using their native Mega Stones even if the Mega Stone is banned, unless otherwise stated.
- Full Pokedex and move list are usable. This includes moves like Core Enforcer, Pursuit, Return/Frustration, and many others.
- Z-Crystals can be used.
- Rapid Spin is 20 BP and does not increase Speed.
- Grassy, Electric, and Psychic Terrain boost is 1.5x instead of 1.3x.
- Defog no longer removes Terrains.
- Inner Focus, Oblivious, Scrappy, Rattled, and Own Tempo no longer have immunity to Intimidate
- Disguise does no damage to Mimikyu after activation.
