Does the Movedex not show enough?

Question

Idk if this is a glitch but... something weird happened this is unexplained in the Movedex.
Here's the series of events:
A Wild Exeggcute Appeared!
Go! Aegislash!
What will Aegislash do? ...
The wild Exeggcute used Worry Seed!
But it failed!

It doesn't say it in the Movedex entry for both Worry Seed and Stance Change, but do moves like Worry Seed, Gastro Acid, etc. not work on Aegislash's Stance Change?
Also, does Skill Swap fail on moves that Worry Seed, Gastro Acid, etc. fail on, like Multitype and RKS System? (I'm gonna assume RKS System is the same thing as Multitype with different items.)

Comments

Are you asking if moves that remove or change a Pokemon's ability work on, for example, an Aegislash with Stance Change, or are you asking why the movedex doesn't say that moves that change a Pokemon's ability don't work on Pokemon with abilities that change things like type, form, etc.?

It's the same thing for Minior. Shields Down cannot be changed.

Answer 1

Stance Change

Role Play, Gastro Acid, Worry Seed, Simple Beam, and Entrainment fail if the target has the Ability Stance Change. Skill Swap fails if either Pokémon has Stance Change. Stance Change cannot be copied by Trace, Power of Alchemy, or Receiver. Stance Change cannot be replaced by Mummy or suppressed by Core Enforcer. If a Pokémon other than Aegislash obtains Stance Change with Imposter or Transform, the Pokémon will not change Formes.

Multitype

Role Play, Gastro Acid, and Worry Seed fail if the target has the Ability Multitype. Skill Swap fails if either Pokémon has Multitype. Multitype cannot be copied by Trace.
Simple Beam and Entrainment fail if the target has the Ability Multitype. Multitype cannot be replaced by Mummy.
Multitype cannot be copied by Power of Alchemy or Receiver. Multitype cannot be suppressed by Core Enforcer.

RKS System

Role Play, Gastro Acid, Worry Seed, Simple Beam, and Entrainment fail if the target has the Ability RKS System. Skill Swap fails if either Pokémon has RKS System. RKS System cannot be copied by Trace, Power of Alchemy, or Receiver. RKS System cannot be replaced by Mummy or suppressed by Core Enforcer. If a Pokémon other than Silvally obtains RKS System with Imposter or Transform, the Pokémon will copy the form of the target Silvally regardless of its own held item.
