I forgot to take a screenshot…but the problem should be easy to reconstruct.
I played Archivist Elysiana (discover 5 cards, replace your deck with 2 of each). And One of the cards offered was Escaped Manasaber which shouldn’t be released until over 4 weeks.
Seems the manasaber…escaped your attention
badum tss
But honestly. It did happen.
All cards are already released and you can craft and use them. The Adventure where these cards can be got as a prize is not released yet but that’s a different thing.
This is not true, I just tried looking at Escaped Manasaber in my collection, and the only way to see the card is to select “Include Uncraftable Cards” while in crafting mode.

Thus, I would think it should not be available through the Discover mechanics as well, but that is for Blizzard to decide.
Yep, you are right, sorry.
Actually, it is.
Adventure cards are always uncraftable, at least until you unlock the plain version (at which point either the golden or both versions become craftable), until the adventure rotates out of standard.
All adventure cards were released. That’s why you can see them in the collection, when you search for uncraftable cards. When you search for craftable cards on an account that has not finished the first wing, you’ll see no cards at all, not even those from the first wing, since they are uncraftable.
