Ho Oh

Ho-Oh is a unique Pokemon in the Anything Goes metagame whose versatility lets it perform a variety of different roles. It can function as a wall, a wallbreaker, or a revenge killer depending on the needs of its team. Its unique typing and natural bulk let it check some major offensive threats, including Xerneas, Necrozma-DM, and most Calm Mind Arceus formes. It also shuts down many defensive Pokemon such as support Arceus formes, Steel-types like Ferrothorn, Skarmory, and Celesteela, and defensive Primal Groudon, being able to remove entry hazards versus them. Regenerator makes Ho-Oh incredibly hard to wear down without Stealth Rock support or great offensive pressure, meaning defensive teams that rely on indirect damage to pressure foes often struggle to break past it. Ho-Oh's STAB combination paired with Toxic also makes it very difficult to safely switch into, especially if it's running an offensive set, outside of a few select walls such as Zygarde-C. However, Ho-Oh has a crippling 4x weakness to Stealth Rock, so teams that include it usually need to provide strong anti-hazard support. It's easily overpowered by common offensive threats like Mega Rayquaza, Primal Kyogre, and Ultra Necrozma. Ho-Oh also has a poor matchup against the ubiquitous Zygarde-C; defensive sets can sponge Ho-Oh's attacks indefinitely, while Dragon Dance sets can use it as setup fodder.
