This is a prime item card in Rebel Clash. Scoop Up Net will see play in every single deck that runs non-V and non-GX cards.
Players that run Blacephalon or Jirachi Prism combo decks will definitely have a blast playing Scoop Up Net. This not only implies the obvious "return to hand in order to heal," but also a few other tricks that require you to scoop out Pokemon from the active spot.
The current price is as high as it goes for item cards, so even if this does as well as expected, you should still wait before the price settles at a slightly lower margin.
