Jirachi

Jirachi is known for its ability to grant wishes, and it's quite possible that it wished to be strong in PvE because Doom Desire's PvE stats got buffed before its official release. Unfortunately, Doom Desire isn't enough to bring Jirachi to the top of the meta as its overall stat distribution is insufficient for offensive PvE.

Best PvE Offensive Moveset

• Confusion is the fast move of choice, outperforming Charge Beam even against most Water-type targets.
• Doom Desire is incredibly powerful even if it would hit for neutral damage, though it doesn't synergize as well with Confusion. 
• Psychic allows Jirachi to act as a Psychic Type attacker, though it's not the best choice for that option.
• Dazzling Gleam and Aura Sphere are good moves, but they lack utility and power on Jirachi.

Confusion's high damage and good energy gains makes it a much better option than Charge Beam.

Doom Desire is the main charge move for Jirachi, and even after its pre-release nerf it's still an excellent move. Aura Sphere is an excellent addition to Jirachi's movepool, allowing to punish Dark- and Steel-type Pokemon who otherwise give it trouble. Jirachi's other moves, Dazzling Gleam and Psychic, simply pale in comparison.
