So it seems to be as I thought: a "mash up" of excess cards from Japan, including recent deck promos (Ninetales-EX, Vaporeon-EX, Jolteon-EX, etc.), the Pokekyun Collection mini-set (the "second Radiant Collection"), and most likely the Premium Champion set (the Articuno full art reprint from Roaring Skies , the Basic Energy)
However, the prices of the four versions aren't the same, with the Lauren YS version coming in at $9.49 retail, while the rest of the bunch sell for around $7
Their goal is to help the player take down Team Star, a group of squad bosses scattered across the region
Now a card with this kind of effect is just a joke
Talking from an investment point of view its very clear that PSA 9 gold stars will eventually reach $15k-$20k in the next few years
