Magic Bounce is bypassing accuracy check.

Stun spore and will-o-wisp not only hit hatterene every single time, but also hit on the bounce back every single time. Tested in other games a few times. Added clefable to help sanity, to prove that the move can indeed miss. Used stun spore / will-o-wisp / toxic 100+ times and never missed on the attempt or the bounce back. According to bulbapedia the bounce back should indeed be able to miss.

Are you able to replicate it? If so, how?
Use status moves vs Hatterene.
Always hits and always bounces back.
 
Immunities like Flash Fire vs a fire move, being grass type vs a powder move, and Magic Bounce itself are all checked before accuracy, so those moves couldn’t ever miss in those situations. Toxic is the opposite, in that it can’t miss when used by a poison type but can miss when used by Hatterene against a poison type. However, you only bounced Toxic back 5 times in this battle, which isn’t conclusive for a 90 accuracy move.
