Pokemon GO Azelf counters are pretty well known, but Pokemon GO's specific battle system lends itself for a more complicated version.
Azelf is one of the latest legendary Pokemon that joined on May 2.
Psst... If you’re extraordinarily lucky, you may encounter these extremely rare Legendary Pokémon in the wild in their different regions even after the event. Good luck—and don’t forget to share any legendary encounters on social with #PokemonGO!
