Diggersby is arguably the best regional rodent (are rabbits even rodents), it has the overpowered ability huge power, combine huge power and choice band you get the Wrath of a thousand gods. If you want to be able to use more than one move per switch, you can easily just use life orb over choice band which would make it a revenge killer if you choose quick attack over Iron head. It's not really that strong but it's the best regional rodent, that's why it's in RU.
