The Iron Bundle raid battle has arrived! It took a bit to figure things out, but for this battle, I used a Goldengho with 252 EVs in Special Attack and Special Defense, Modest Nature, holding a Shell Bell. Its moveset is Light Screen, Nasty Plot, and Make it Rain.

Overall, it will keep on using Hydro Pump on you, so it has a chance to miss. With that, I am able to use Nasty Plot and Make it Rain to victory.
