I mean, when you compare it to things like Cavern Shinyfinder and Corsair Cache, it's safe to say this is the sort of card that enables archetypes. That said, my knowledge of those two cards suggests that there's usually a specific weapon you're looking for (Spectral Cutlass or Kingsbane for rogue, and Ancharrr for warrior). I think Shaman has some options already in use that could be impactful enough, such as The Fist of Ra-den, Jade Claws, potentially (though perhaps that's too weak of an option to sub in for existing jade options).
Now, that said, with some of the new options we've been given (the attack synergies), it could be that simply having a more reliable way to acquire weapons is worthwhile. In wild, I could imagine this card in Even Shaman, but in standard, I wouldn't expect the synergies to be strong enough to really take hold of the meta. (Grain of salt, obviously, I've been entirely wrong about these things before)
