- Sunny Day
- Hidden Power [Ice]
This thing just sets up all over weathers face. It has Magma Storm to trap the enemy and to deal with Abomasnow, Solarbeam to take care of TTar and Hippowdon after Sunny day, and HP ice for coverage.
IMO, Magma Storm and Sunny Day sets are the best ways to trap weather without a weaksauce Duggy.
