Needs Triage Bug Report - Mechanics

[komibebop]

What type of bug are you reporting? Mechanics

What is the bug?
Apparently, using the move "Skill Swap" in a pokémon with the Ability "Pressure" results in both pokemon having pressure, instead of them changing abilities, or even in the move failing.

Are you able to replicate it? If so, how?
Using the move "Skill Swap" in another pokemon (from my experience, at least from your own team), which has the ability Pressure. This was tested in Format VGC 2024 Reg G, using a Mewtwo, using Skill Swap, in a Golurk, which had the ability No Guard. I couldn't find this happening to other people, nor in the moves or abilities page here in Smogon.

Here's video of this happening in a custom match:

Last Resort failed because it only works when the user has made use of all its other moves. The "But it failed" message shows that the move failed to function, not that it missed.
Also, the replay never shows that your Pokemon had Pressure at the same time? Could you point at why you believe that?
