Groudon

Primal Groudon is a powerful bulky attacker when equipped with Red Orb, which leaves it with only a Ground-type weakness and a STAB V-create that can OHKO even relatively bulky targets that take neutral damage, such as Mega Audino, Xerneas, and Mega Mewtwo X. It is also offensively versatile, with a wide choice of viable coverage moves such as Fleur Cannon and Bolt Strike that enable it to lure in and weaken otherwise reliable checks such as Giratina and Celesteela, respectively. Its base 180 Attack and base 150 Special Attack are excellent for mixed attacking sets as well, and Desolate Land's Water immunity gives Primal Groudon more opportunities to switch in. Excellent bulk and typing also let it tank hits from powerful attackers, such as Primal Kyogre, Mega Diancie, and Regigigas, and OHKO them back. However, it is initially quite slow, so it struggles against faster Pokemon such as Mega Mewtwo Y and Kyurem-W that target its weaker special bulk. It also is normally checked by some ubiquitous defensive Pokemon such as Zygarde-C and Giratina, but though it bypass them with the appropriate coverage moves on mixed sets or force them to switch in and give momentum to the Primal Groudon user. Lastly, it is fairly one-dimensional, as its item and ability are restricted to Red Orb and Desolate Land, though it still carries staggering power despite these limitations.
