Is shadow Moltres good in Pokémon Go?
There are only a handful of shadow Pokémon in Pokémon Go and even fewer legendary ones. Because of the increased attack stats, the shadow version of any legendary Pokémon is typically considered a better option, but in a few rare cases, that’s not true. When it comes to shadow Moltres, it’s nearly on par with its original version. The biggest issue is trying to remove its frustration from the charged attacks to increase its damage output. If you can do that, shadow Moltres is a better option and is a Pokémon we recommend you add to the collection, so long as it has the best moveset.
