[SET COMMENTS]
- Primal Groudon is a potent mixed attacker thanks to its amazing stat spread, its Ground / Fire typing, and its expansive movepool. It switches into many staples, like Ferrothorn, Necrozma-DM, and Eternatus, and this breaks holes in many teams early-game if healthy enough.
- Eruption allows Primal Groudon to deal strong damage to foes that don't take as much damage from Precipice Blades, such as support Arceus formes like Arceus-Ground and Arceus-Dark, as well as Ferrothorn, and Xerneas. Eruption can also 2HKO foes that resist Fire, like non-defensive Eternatus and Zygarde before Power Construct.
- Precipice Blades is Primal Groudon's secondary STAB move, hitting Zacian-C, Primal Kyogre, and Necrozma-DM more reliably than Eruption when Primal Groudon is chipped.
- Rock Tomb can be used to deal super effective damage to common switch-ins, such as Ho-Oh and Mega Salamence, while also giving Primal Groudon a form of speed control against foes like Eternatus and Yveltal. Alternatively, Stone Edge can be used to deal heavier damage against Giratina-O and OHKO Ho-Oh after minimal chip damage.
- Swords Dance is recommended to reliably OHKO Necrozma-DM, Primal Kyogre, and Eternatus with Precipice Blades after a boost, while also 2HKOing the majority of its checks, like Arceus-Ground and Zygarde-C.
- Stealth Rock is an alternative that can be used to soften up opposing staples like Arceus-Fairy, Arceus-Ground, and opposing Primal Groudon while also heavily damaging Mega Salamence and Yveltal. It also allows Primal Groudon to reliably OHKO Marshadow and Rayquaza after Stealth Rock damage.
- Eruption Primal Groudon fits best on bulky offense teams that appreciate a mixed wallbreaker that can blow holes in the opposing team early-game.
- Although Primal Groudon is a threatening early-game wallbreaker, it still cannot deal with the likes of Arceus-Ground, Zygarde-C, and Palkia-O, so it appreciates teammates that can deal with them, like Primal Kyogre, Palkia-O, and Arceus-Fairy.
- Primal Groudon appreciates entry hazard support from Eternatus and support Arceus formes like Arceus-Dark and Arceus-Ground, as they can chip most of Primal Groudon's aforementioned checks. In return, Primal Groudon can deal with Zacian-C and Primal Kyogre for them respectively.
- It's important to keep Primal Groudon from needlessly being chipped, so having a teammate with entry hazard control such as Ho-Oh or Yveltal, is beneficial.
