Yeah , i'm wondering how you can be stuck with 3 powerfull mons against her. You're asking for special mons just to be able to beat her but as Wolfox and Jess said they are multiple pokemons around lapis ward such as boldore who can easly destroy her.
But it's my bad , i should have read the topic more properly. No matter , i will keep the 5iv ghasty and 5iv torchic for someone else.
