You roll in 2 instances.

1. When there is a limited servant you want. 2. When there is a rate up servant you want.

If you really want Mordred and Tesla, you should roll. The chances are that you'll have multiple rated up servants that you truly want isn't too common so the only thing to weigh against is the possibility of a limited servant later that you want really badly. But I'd say do one 10 roll here since there's so much you want. Goldfish CE also seems to drop a lot for me and my friends to the point that I limit broke it just because I had so many. And no, I'm not a whale. Just wanted (and got) Mordred.
