Sinistea has two forms: Phony and Antique, often called the fake and real forms, respectively. They can be distinguished by either:
- The item required to evolve it. Phony form requires a Cracked Pot, and Antique form requires a Chipped Pot
- A mark of authenticity. Only the Antique form has this. This mark is on the bottom of the cup, appearing as a grey seal inside the rim at the cup's bottom.
The mark of authenticity is difficult to spot, so often the first is the easier way. But this requires catching Sinistea.
If you find a wild Sinistea, can you distinguish the two forms apart in the wild? For example, can you see the mark of authenticity on wild Sinistea as the battle camera changes?
