146 Moltres(Galarian)

Both Fast Moves have identical stats, and thus either can be chosen depending on whether Dark or Flying coverage is preferred. 

Brave Bird is the most useful Charge Move available, threatening massive damage with a moderately high energy cost and applying a self-debuff. Payback demands slightly more energy, but deals strong Dark-type damage if unshielded. Ancient Power is Galarian Moltres's lowest costing move, but it sacrifices a ton of coverage and damage and is generally not worth it.

Galarian Moltres actually has a decent stat product, being comparable to Nidoqueen and Obstagoon. Its nuke-exclusive moveset holds it back, however. With many Pokemon in this league possessing spammier movesets, Galarian Moltres can struggle to keep up, and it doesn't have the insane bulk of Azumarill or Registeel to fully support that kind of playstyle. It also faces direct competition with Mandibuzz or XL Vullaby, with the latter even having access to Brave Bird.

Thanks to the increased bulk in Ultra League, Galarian Moltres can reach its devastating nukes more consistently. In that sense, it can be even more threatening than Mandibuzz, as it packs enough damage to potentially overwhelm its counters when given farm opportunities. Though its heavy damage playstyle is inconsistent, Galarian Moltres's closing potential is still worthy of respect.

Unfortunately, Yveltal exists, and does whatever Galarian Moltres wants to do but better. Its performance isn't even close to being as good as Yveltal's, taking away the potential of running an ABB style team with it and Yveltal.
