[@Parallel Hearts] I'd be somewhat interested in Berserker or Shielder, but it seems those spot and the others here filled up fast. TwT

So instead, i'd like to ask if any other "extra" classes would be allowed, maybe as some oddity in the Grail War? Not anything like Foreigner that are one of FGO's unique quirks, but even something like an Avenger or otherwise could be interesting potentially, etc. :3

Would something like that be possible for a servant if i made a master as well, albeit not necessarily for that servant, to help on that end of things too?
