Green series Competitors often stand as a separate tile next to blue and gold. On PKSOVA this is the category green series and the neighboring places of power.
Blue, lilac and gold rulers are numbered in literature. Green cards are often personalized. The name of the series is the manufacturer's catalog label, not a diagnosis.
Check the photo and series with the card, not with the retelling in the chat.
It is easier for a beginner to start with blue series.
