Hello! First, let me preface this by saying that I have, in fact read quite a bit on how to beat her.
The problem is I saw many people use things like trick room and rain dance.
My team is:
Visul (Espeon)
Psychic
Morning Sun
Swift
Curse
Cedric (Blaziken)
Flare Blitz
Bulk Up
Brave Bird
Hi Jump Kick
Rhosymedre (Roserade)
Petal Dance
Growth
Aromatherapy
Synthesis
Cheryl (Ampharos)
Power Gem
Thunder Wave
Discharge
Dragon Pulse
I also have a Sharpedo with Crunch and Aqua Jet, but Aqua Jet is quite weak and it gets 1 shot by everything after that. So does the rest of my team. I wold love to be able to go back to Reborn City to find some pokemon (Rotom, something with earthquake) but I don't think I'm able to. Trick Room Bronzong is pretty much out, as Blaziken and Espeon outspeed her pokemon. And Rain Dance is pretty much out, as Sharpedo gets exploded by everything. Are there any other options for strategies people could help me with? I know my team isn't great, but I just picked my favorites and was previously able to get by due to Roserade and Blaziken being OP.
So I've pretty much hit a wall since all my pokemon nearly get 1hko'd and I'm a terrible trainer...
