Wow.. even though its not great in a tokens version of it, it still made me think about aristocrats. Between mayhem devil, grim initiate and cruel celebrant.. there's certainly some strong tools for an aristocrats deck. It's like they made stronger versions of all the non-sac outlet parts of an aristocrats deck, but not the outlet part.
The priest of forgotten gods is good, but a little slow and dies to removal too easily. Maybe instead of being a full on aristocrats style, it's more like a midrange mardu token deck with an aristocrats sub-theme.
Then again, things never seem to end up the way they look halfway through a spoiler season. Everyone thought judith was gonna make a RBx deck viable in standard, but after the first few weeks that didn't pan out.
