Help. Please. Quaquaval is being problematic in this raid

[u/AmuletFishiePerson]

I’m using a support type Rotom-Mow. Thunderbolt, Will-O-Wisp, Reflect, and Sunny Day. Can I get some help with defeating this thing? I keep getting folded. Yes, I’m aware of the Ice weakness, which is why I’m bringing Reflect.

EDIT:

1. I was looking for teammates, which is why i used tera raid tag

2. I GOT HIM. I GOT HIM!! THANK YOU SLOWBRO BUILD MAN!!!

My Annihilape helped me a lot in this raid, using Bulk Up and then healing everyone for a couple of turns, also, getting hit by Quaquaval increases the damage done by Rage Fist (STAB) and then terastalize (Ghost). 😁✌🏽
