Jirachi

Jirachi's incredible Steel / Psychic typing and its base 100 stats across the board let it fill many roles, from a specially defensive wall to a Choice Scarf pivot. Serene Grace lets Jirachi perform its roles even better, as its offensive moves have twice the chance to inflict their secondary effects, most notably giving Iron Head a 60% chance to make the foe flinch. Jirachi's movepool is arguably its best asset, with incredible coverage and support moves, such as Fire Punch and Healing Wish.

While Jirachi's typing lets it wall Fairies extremely well, it leaves it with some glaring weaknesses, particularly to the ever-common Ground-, Fire-, and Dark- types. As such, Colossoil, Heatran, Garchomp, and many other Pokemon force it out with their STAB moves. Although Jirachi's base 100 stats are great for defensive roles, they fail to stand out offensively, forcing Jirachi to rely on super effective coverage, Toxic, and Serene Grace to deal any notable damage.
