I'd like to point out that by the same logic statues shouldn't be Artifacts, as they start as Lands. Plus, it is the best fitting permanent type and not worth creating a new one (sorry Tarmogoyf).
As for the Wildered Quest, I felt it was meh. The story is sometimes confusing and many plot points were pure deus ex machine and overly abrupt nonsense, but the characterization was nice. I think that the poster above me is being a bit harsh on the Kenrith twins, and I especially think that they are being harsh on the Kenrith parents, who are overall pretty good people. One thing I will note is that it actually makes the commercial (which I think was better) non-canon, as Garruk is never captured and brought to Castle Ardenvale (and it feels highly unlikely (considering the events of the story) that he ever would be). I actually think that the lore wasn't as well done as it probably should have been. Also, it probably means that Battlebond happened well after WAR.
