I tried evolving Vullaby into a Mandibuzz when I played Black 1 like fourteen years ago, but I ended up boxing the poor thing because it took way too long to evolve and the payoff wasn't really worth it.
I'm thinking about making a monotype Dark team when I play Blaze Black, because I want an excuse to slap a Hydreigon onto my team. Maybe I'll give Mandibuzz another chance there.
