Hey! TNT has started allowing for the creation of what's gotten termed "replica UCs" for people who lose a UC in a reversal. They had been letting people fish a pet from the pound and UC-ing it to mirror whatever pet they lost, but people started abusing this (having a friend drop a RW in the pound and immediately adopting it, for instance, to game the system) so now they only allow replicas to be created from brand new pets.
UCs are supposed to become more accessible in the near future (we hope...). There's going to be some kind of Neocash option for them. The rumor is we should get news after this upcoming Faerie Festival. The specifics of how new UCs are going to work, or really any other details about them, are unfortunately still unknown.
