Mr. Mime

Mr. Mime => is Pokemon dex #122 (Pokemon Regional)

Opendex
=> Pokemon you already have/are registered in your Pokedex, displayed as an image along with the Pokemon's details

Non-Opendex
=> Pokemon you do not have/are not registered in your Pokedex, displayed as a black shadow (meaning you've seen it in raids/gyms) or as a Pokedex number

Requirements for Trading Opendex:
1. Must have 100 Stardust
2. Must have the Pokemon registered in your Pokedex

Requirements for Trading Non-Opendex:
1. Must have 100 Stardust
2. Must be a shadow (unseen) or unowned Pokemon

Note => Tip for Non-Opendex (Legendary Pokemon/Shiny Pokemon): Willing to wait until Ultra Friends to reduce Stardust cost (80,000 Stardust). If willing, purchase the cheapest or preferred Opendex Pokemon from Wantau Store, then message the seller to request a 30-day friendship (Ultra Friend).
