theres quite a bit more to it. the discover effect on this card is far stronger than most other discover effects. discover in general tends to be balanced around the fact that in roughly any category of cards theres gonna be a lot of bad cards to dilute the pool of good drops. this card doesnt suffer from that because the vast majority of the time your opponent will run mostly good cards. it also lets you look at your opponents deck and can give you info thats impossible to get otherwise (ie, see a legendary in your pick? now you know your opponent doesnt have it in hand). you can spy tech cards they might have and more effectively play around them. all of that on top of dragon tag, vanilla stats, and a value effect and you have easily one of the best cards printed currently.

The fact that some people voted this as "meta-defining" is baffling. It's playable at best
