I’m like the resident Trick Room enjoyer, and honestly, I think TR is LESS viable in OU post Home, and mind you, I believed this to be true before Magenera got banned. Ursaluna is a stupendously good breaker, I’m not going to lie, but full TR is not sustainable in this meta, as the playstyle is struggling to leverage its bulk because of Samurott-H.
Prior to Home, Sash Hatterene was a great TR lead specifically because it could set TR, deny hazards and either start attacking or off itself with Healing Wish to get a breaker in. This early to mid game hazard denial was really important to the TR game plan flow chart.
Hat cannot stop Hamurott from Spiking on it, so its teammates are constantly getting chipped by Spikes. So what are they supposed to do, run HDB or hazard control? Both are bad options for TR mons and setters need things like Mental Herb, Lum Berry for Spore etc, while breakers need damage boosting items.
Tl;dr: Ursaluna is not close to broken, because full Trick Room is bad in the Samurott-H HO meta.
