Ravenous Ghoul eating ability

[Battlehamster]

So Ravenous ghoul can, as a quick action, while in a zone where a creature previously was destroyed this round, can remove that creature from the discard pile to gain a growth marker.

So my question is, if that creature was obliterated, reanimated etc (ie was destroyed but card is not in the discard pile) can he still "eat" that creature since it was destroyed it just won't be able to remove from the game?

Taking them from the discard pile and removing them from the game is a requirement for the Growth marker. If it can not do this, it can not gain the Growth marker. In both cases you listed, the target would not be in the discard pile and thus would not be legal.

Zuberi is correct. He has to actually eat the corpse to gain all of its courage, rich tasty courage... I mean growth marker... yea that's what I said.
