I'm kind of torn between him and
Lotleth Troll, since I only have so many Golgari spots available, and they're fighting for the same small-creature slot. So I haven't tested
Varolz yet, but I'd also like to hear from people who do. The Troll seems more flexible and easier to jam into any deck playing green and black, while the troll feels like a Johnny-build-around that would only fit into a couple of narrower builds.
Err.. you know what I mean. Jason's sac-happy cube would be as good a home as any for the Golgari champion.
