Pokemon Reborn Monospecies Golduck - Florinia gym battle redo

Yesterday I posted chapter 2 of this run including the Florinia fight. What I didn't share is that I had a slightly more interesting and more efficient win set up which unfortunately wasn't able to work due to a bug in the game. The bug has now been fixed, so I was finally able to make it work.
As can be seen in the video, the fight is mostly the same until Cottonee hits the field. After Encoring it, I go for Wonder Room this time. For those unaware, Wonder Room swaps the defense and special defense stats of all pokemon for 5 turns.
Both Cottonee and Breloom have significantly higher defense than special defense in this fight, which meant that I could not oneshot Cottonee at all, and I could not oneshot Breloom without a gem boost in the previous win.
The gem I used up took away the opportunity to use another until after Corey.
Funnily enough, while test fighting Corey today I noticed that for the fight to be most efficient, I actually need that gem, which was a big motivator to redo the Florinia fight.
Anyway, using Wonder Room instead of just attacking here allows me to oneshot both Cottonee and Breloom without the need of a gem, as can be seen in the damage calculations below:
Lvl 25 252+ Atk Silk Scarf Psyduck Facade (140 BP Normal) vs. Lvl 24 36 HP / 36+ Def Cottonee: 45-54 (73.7 - 88.5%) -- guaranteed 2HKO

Lvl 25 252+ Atk Silk Scarf Psyduck Facade (140 BP Normal) vs. Lvl 23 34 HP / 34 Def Breloom: 48-57 (77.4 - 91.9%) -- guaranteed 2HKO
Lvl 25 252+ Atk Silk Scarf Psyduck Facade (140 BP Normal) vs. Lvl 23 34 HP / 34 Def Breloom in Wonder Room: 60-71 (96.7 - 114.5%) -- 81.3% chance to OHKO
