Chansey is a really good Eviolite user. It's used over Blissey a lot of the time, as it can do everything Blissey can, while also getting even more bulk than Blissey.
Doublade @ Eviolite
Ability: No Guard
EVs: 212 HP / 252 Atk / 44 Spe
Adamant Nature
- Swords Dance
- Iron Head
- Shadow Sneak
- Close Combat
Doublade's fantastic typing and good Eviolite-boosted bulk make it a solid check to many top threats, allowing it to switch into foes such as Cobalion and Swords Dance Lucario with ease. In addition, its decent Attack stat, reliable priority in Shadow Sneak and access to Swords Dance allow it to act as a formidable late-game sweeper once its checks, such as Incineroar and offensive Galarian Weezing, are sufficiently weakened.

Other potential good ones I've seen around:
Porygon2 @ Eviolite
Ability: Trace
EVs: 252 HP / 4 Def / 252 SpD
Calm Nature
- Ice Beam
- Thunder Wave
- Recover
- Teleport

Dusclops @ Eviolite
Ability: Pressure
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
- Toxic
- Seismic Toss
- Rest
- Sleep Talk

These last two are lower tiered, and likely aren't as viable.
Corsola-Galar is also pretty good, but Smogon doesn't currently have a set for it in OU. Hope I helped!
Edit: According to sumwun, Doublade wasn't used at all often recently. While it's apparently still worse than Aegislash, it's likely still a decent Eviolite user.
