[Stuck at Narcissa (Intense mode)]

I always feel like I'm completely stuck at Narcissa because her mismagius keeps destroying my team while scoffing off the damage my pokemon unleashed. I need some tips or some pokemon that could at least punch a hole in her team without damaging mine too much

Here's my team and it's movesets(They're all Lv 35 by the way):

Samurott : Covet, Razor shell, Aqua jet, Revenge

Nidoking : Sucker punch, Megahorn, Toxic Spikes, Double kick

Rimbombee : Dazzling gleam, Pollen puff, Stun spore, Magical leaf

Electrode: Electro ball, Signal beam, Light screen, Flash

Hariyama: Fake out, Knock off, Force palm, Rock tomb

Talonflame: Flame charge, Roost, Peck, Quick guard

[Rift Aleita (I think I'm just an idiot)]

You can use sylveon to set up misty terrain to stop the power drop to fairy moves in the dimensional field, Erin's Florges and Absol's play rough can wipe out the golems since they are quadruple weak to fairy. You just need to watch out for Aelita's gunk shot while setting up the misty terrain and don't use the magical seed since the golems are much slower than your sylveon.
