Jolly/Adamant Nature
- Hone Claws

- Sucker Punch
I’ve been using this pairing on a hyper offense build and they compliment each other quite well imo.
1) Groudon can paralyze a lot of yveltal annoyers, such as etern, xern, and other yveltal, paving the way for set up
2) Yveltal in turn threatens giratina, lunala, tangrowth, and knocks lando/zygarde, making them much easier for groudon to eventually muscle through. It also threatens faster pokemon like calyrex and offensive ogre with sucker punch.
3) Sky attack actually has a 30% flinch chance, so if groudon misses a stone edge vs something like ho-oh or other yvel, you can still potentially get a paraflinch cheese KO
