This is the current 35 point list that I am running with her and have had a great deal of success with - If you want you can hot swap janissa and the krielstone as desired and character restrictions will allow. I really like Janissa in there for all the reasons everyone loves janissa in every list. I pulled her out because my 2nd tourney caster needs her more.
Another variation with is dropping the stone scribe elder and the feralgeist and adding the stone scribe chronicler. I have had a lot of fun and success with all the above.
The bump to 50 simply drops the feralgeist and adds horthol and max longriders.
