New type: Psychic/Dark
New moves: +Dark Pulse, +Memento, +Parting Shot
Justification: Oranguru uses its cunning mind to try bend other Pokemon to its will.
New type: Silvally's Memories are changed through a form change and do not take up an item slot (similar to Rotom). The memories cannot be removed, only changed. Silvally keeps Type:Null's ability, Battle Armour
New Moves: +Recover (Psychic), +Extreme Speed (Fire), +Stealth Rock
Justification: Silvally's RKS System is now a intrinsic feature of it design. This allows Silvally to fully realise its potential in fighting Ultra Beasts without restrictions.
New type: Steel
New Moves: +Recover, +Stealth Rock, +Yawn
Justification: Type:Nulls is forced to wear a metal mask which restricts its ability to fight. It loses both its mask and Steel type when it evolves.
Revelation Dance
New type: Varies/Flying
Justification: Birds often dance as a part of their mating rituals. Revelation Dance still takes on the users primary type but adds Flying to the effectiveness of the move (like Flying Press).
Spotlight
New type: Dark
Justification: This move tricks opponents into attacking the user's ally.
Me First
New type: Psychic
Justification: Since the user executes a move before its target, some sort of mind reading must be involved.
