"We have some exciting deathrattle build-arounds coming soon" doesn't sound encouraging

That was some of the text in the explanation of Sylvanas moving to Wild.

Sylvanas wasn't a build-around card though. In fact, up until WOTOG, build-around cards weren't THAT common of a thing, but since then, they have become RAMPANT. C'Thun, N'Zoth, Jade, Reno/Kazakus, and Patches/STB.

Sylvanas was a high skill card that fit into a specific set of decks. The opposite of "Build-around" cards because it required a brain to include.
