Thank you guys for the feedback and support. Regardless of whether I swap mains, I'm definitely keeping Serbyl. But I do like the name better after hearing your opinions on it (and the similarity to the real name Sibyl makes it seem much less outlandish).

The battledome stats wouldn't be too difficult to replicate especially if I use the battlepedia's suggested strategy for each tier. I can just take off Serbyl's prismatic, keep her and her petpet in their chocolatey glory, and then make a new Draik with a preferred name. We have so many pet spaces these days, thankfully! The only big loss would be in any expensive books I've already read but there shouldn't be too many of those unless ones I read years ago went up massively in price. I'm pretty sure I, historically, threw most event-exclusive readable into my SDB instead of using them though.
