Ho Oh

Ho-Oh's main niche is a check to strong special attackers such as Mega Mewtwo Y, Mega Gengar, Pixilate Mega Diancie, and Gale Wings Mega Rayquaza. It has a good Attack stat that gives Ho-Oh reasonable offensive presence. Its typing is also reasonably good, as offensively, Fire and Flying have good neutral coverage, only missing out on Rock-types and Flash Fire Steel-types. Defensively, two of its weaknesses in Water and Electric are uncommon, and the Fairy-type resistance allows it to check Pixilate Mega Diancie.

However, Ho-Oh's main drawback is its low physical bulk, leaving it very vulnerable to powerful physical attackers such as Kyurem-B, Mega Mewtwo X, Regigigas, and Mega Tyranitar. Furthermore, its 4x Stealth Rock weakness limits Ho-Oh to running Magic Guard sets and thus preventing it from running other, arguably better, abilities. The presence of Diamond Storm + Poison Heal Mega Tyranitar, which is able switch in on Ho-Oh's STAB moves and easily KO back with Diamond Storm, is no help either. Thousand Arrows also leaves Ho-Oh vulnerable to other Ground-type moves.
