Mewtwo = Pokemon dex #150 (Pokemon Legendary) Opendex = Pokemon that you already have/registered in your Pokedex, displayed as an image and Pokemon details. Non-Opendex = Pokemon that you don’t have yet/not registered in your Pokedex, displayed as a black shadow (meaning you’ve seen it in raids/gyms) or as a Pokedex number. Trade Requirements for Opendex: 1. Must have 100 Stardust. 2. Must have the Pokemon registered in your Pokedex. Trade Requirements for Non-Opendex: 1. Must have 100 Stardust. 2. The Pokemon must still be a shadow or unowned. Note: Tip for Non-Opendex (Legendary Pokemon/Shiny Pokemon) – Be willing to level up friendship to Ultra Friend to reduce Stardust cost (80,000 Stardust). If you agree, buy the cheapest or your preferred Opendex Pokemon from Wantau Store, then message the seller to initiate a 30-day friendship (Ultra Friend). How to Trade Opendex or Non-Opendex?
