So I just logged into the Blizzard app and found this advertised:
If you ever wanted to see Lego World of Warcraft, well this is as close as I've seen.
Was this already posted or is it news? It's fan made but supported by Blizzard, who make Warcraft.
P.S. It's a trailer for the new Hearthstone expansion pack card, Saviours of Uldum.
