I like it, and I don't like it. I think it suffers from the same problem that many ideas suffer: it has a great mechanic but not so great theme.
I like X card thing very much. Nice synergy with
. But the theme is almost like a random word slapped on it. I mean why does a Ghoul have this mechanic? Why does a Ghoul do more damage if you have more cards? Maybe I'm missing something but it doesn't make sense to me.
With a better theme, this card would be great. Now it just.. meh. I know many players say "gameplay > theme", but I say why not have both?
