7 mana Mogu Fleshshapers (with no art) are available again alongside the usual 9 mana ones…
Wasted 200 dust making some, made a deck with all 4 in, queued with it, they work fine. Just guessing they shouldn’t be there.

Sounds like the card is completely usable aside from the missing art, as long as you're playing Wild format (even though the original is standard, the new one is in the Brawl set which isn't). The card ID indicates that it's intended for an upcoming Hall of Champions brawl.

This was hotfixed.

We’ve resolved another issue where players were seeing an incorrect version of the card Mogu Fleshshaper that was missing art. You should no longer be able to acquire the incorrect card in the game.

The carddefs don't reflect the change, but the collection no longer shows the bugged card.
Additionally, dust should have been refunded for anyone who crafted it:

Dust for the incorrect card should have been automatically awarded as of earlier today.
