Desecration Demon when it was revealed, only for it to end up being a staple in mono-black devotion.
Clackbridge Troll functions somewhat similarly - on one hand, it provides its own food (instead of being shut down by
Lingering Souls), and gives you a net negative when faced with immediate removal. (although the 0/1 goats are pretty low value for most opponents). On the other hand, drawing cards when your opponent pays the t(r)oll is a pretty major upside. Seems like a fun card, at the very least. Also some great art - those goats look adorable (and delicious).
