The Topps digital trading card app portfolio continues to grow, this time into the world of professional wrestling with WWE Slam. Like their other card apps, Topps WWE Slam lets collectors open digital packs and collect cards of WWE superstars from today and the past. The initial roster includes a broad mix of faces from Smackdown, Raw, NXT as well as retired WWE Legends.

Just like a traditional set of cards, there’s a base set. These are the foundation of the app. There are almost 200 to start, each with a handful of colored parallels — part of the chase element.
