Lacey kind of caught me by surprise and I only won because Orthworm clutched a win thanks to Terastallizing into a Water-type and landing a OHKO on her Fairy Tera Type Excadrill. Murkrow didn't really perform as well as I'd liked it to, I think that was in part due to it being the wrong battle for it but it did help in stalling her Whimsicott. Another issue I had was me failing to use an Ability Patch on my Cyclizar, leaving it stuck with Shed Skin, before starting The Indigo Disk. Thankfully that was something I could easily fix after the match.
Crispin was easier thanks to me correcting a mistake with Cyclizar and using it in a combination with Orthworm, essentially letting it set up two incoming Pokémon with a substitute. After that it was just being smart with Gliscor, Glimmora, and Tyranitar.
I had to fight Amarys twice due to my game glitching out but the results were similar: Murkrow proved to be really helpful thanks to packing a Prankster-boosted Taunt and going with the bulkier Eviolite-supported build made it tanks some moves that would OHKO other Pokémon and Chandelure still takes names. The only difference was how the matches progressed (the first match had Chandelure sweep a good portion of Amarys' team with a defensive Tera Grass Type and some well-placed moves while the second had Gliscor tanking a good amount of hits and dish out some serious damage in return) and how it ended (the first match had Sandy Shocks OHKOing a Tera Steel Type Metagross with a critical, Expert Belt-boosted Earth Power and the second one had Gliscor's Earthquake put Metagross in the red with Murkrow dealing a KO via Foul Play).
