Pokemon TCG Pocket just had a trailer put up. Most of it is what we kind of expect from it, BUT the last 25 seconds had a bit of a more ominous and possibly mystery concerning the Immersive Artwork cards:
Mewtwo is getting one and it looks like it's escaping from a building. On the outset we get to spin the scene around, see Mewtwo from different angles & all the shards of glass from the window Mewtwo is escaping... BUT it then zooms in behind Mewtwo through the window where we see the interior of the room, details we can't even see in the card art.
With how is abruptly ends with a video distortion effect, it makes me wonder if through the Immersive Artworks they're going to set up some mystery and/or background story for players to discover. Many Immersive Artwork cards could have a secret hidden in the scene, unviewable from the card art, that tells a story or secret about the set. Since the first TCGP set is called "Genetic Apex", makes sense Mewtwo to be involved, and if I had to hazard a guess looks like some some not-quite-legit science experiments are maybe going on...
Of course, what is the end goal of this? Just to tell a story? Neat, and something they would only be able to do with physical cards... BUT (yes, I realize this is my third on), being this is an all digital TCG experience, they could have players who piece together the mystery (or read an online guide) unlock hidden cards (or if that's too gamebreaking, maybe alternate artwork). If Pocket is successful, they could even have future Immersive Cards be used to hint toward future things like the next TCG expansion (both digital and physical) and maybe game related topics such as new Pokemon (to name the obvious).
