If you're looking to get your hands on the Immersive art for Mew in Pokemon TCG Pocket, you've come to the right place. This beautiful piece of art is available to only the most dedicated of collectors.

Obtaining Mew

Getting Immersive Mew is quite simple, though no mention of it is made within the game itself as it is a Secret Mission. To complete this mission, you must collect all the Pokemon that are featured on the Kanto Pokedex, or the original 150 Pokemon ranging from 001 Bulbasaur through 150 Mewtwo.

Once you've collected all 150 Pokemon, which can be of any combination of cards that share the same name, its just collecting each individual Pokemon itself that matters, you will get a popup that says "Complete the Kanto Pokedex" and it will display a 150/150 progress bar. The reward is Immersive Mew which is one of the criteria for yet another Secret Mission, The Immersive 4. Here is what the start of the Kanto gallery looks like.
