Weird thread to ask this, but what's a good handful of mons to throw at Winona in an Emerald Nuzlocke? I don't have any Ice type moves or mons, and my luck with the slots/tables are... barely passable. Any suggestions?
Her Pokémon have a lot of Grass, Water, and Steel attacks that would wreck Rock-type Pokémon, so without Rock or Ice, you just have Electric-types.
Electrike is on route 110 and 118, Manectric is on route 118, and Magnemite and Voltorb are in New Mauville. You can also find Magneton and Electrode in there as 1% encounters.
The only other Electric-types that you have access to at this point are Plusle and Minun... but I assume that you want to actually win.
I'm not nearly autistic enough to have Pokémon's learnsets memorized, so I don't know if there are any good Pokémon that get access to random Electric-type moves through the Move Reminder or something, but the first few candidates that I looked up didn't make that idea seem very promising.
If you're trying to get TM24 (Thunderbolt) from the Game Corner and not having much luck, it looks like you can get another copy of the TM from Wattson as a reward for shutting off the generator in New Mauville.
Magneton's Steel-type lets it resist all of Winona's attacks except for Water Gun and Earthquake, so that's probably your best bet. A single leveled-up Magneton with Thunderbolt could breeze through her entire team until her final Altaria.
Altaria would still take Thunderbolts for at least neutral damage, so you could either leave Magneton in and take your chances with beating it (or at least get as much damage onto it as you can), or switch into something else that can take Ground, Dragon, and Flying-type attacks. If you have something else on your team like that, then you can probably beat her with just two Pokémon and a little level grinding.
Sorry if there are any Nuzlocke restrictions that make any of these things non-options. I've never looked into Nuzlockes myself, so I only know about the permadeth part of it.
