Sure thing. I've been thinking about Sudden Bloom quite a bit recently. I think it requires a variant of Big Beast nature that has fewer confused creatures. For example, Starving Sabertooth instead of Overgrown Rhino. Valewarden instead of Moose. Etc. Even still, I'm partial to The Hunt. Sudden Bloom helps you close games, but it's dead if you have no board presence. The Hunt can get you back in the game. I'm not convinced either way, though.
