How to get Phony and Antique Form Sinistea in Pokémon Go
Sinister joined Pokémon Go officially on Dec. 3, 2024, and its two forms also became available for trainers to find.
Unlike in the core games, you can’t just check underneath the cup to see if it has the stamp to prove its form. But there is a way to check whether the Sinistea you caught is a Phony or Antique Form for trainers wanting to collect both.
