Poltchageist and Sinistcha Debut
- Poltchageist and Sinistcha, the Matcha Pokémon, will make their Pokémon GO debuts!
- First discovered in the Paldean region, they are considered divergent forms of Sinistea and Polteageist.
- You can use 50 Poltchageist Candy to evolve Poltchageist into Sinistcha.
Sinistea and Polteageist Shiny Debut
For the first time in Pokémon GO, Sinistea can be shiny! They are a fantastic pale pink shiny, so easy to spot! Sinistea has two forms, the phony form, and the authentic form, distinguishable only by a stamp on their base for the authentic form. Good luck shiny hunting for the shiny authentic form!
