Used fairly she gets around white's card drawing problem by fetching rebels. Mirror Entity is an extremely good threat and many other rebels are pretty good in support roles, I especially like the law- and lighbringer. Used somewhat more unfairly there is also the possibility to fetch up most of the life combo with Task Force and Outrider en-Kor, while there is quite a bit of redundancy in the area of saccing creatures to gain life equal to their toughness. Changeling Hero helps power through mass removal, quite possibly your own.

I've had very good results with my own Lin Sivi powered EDH deck. It rarely loses, though it can take pretty long for it to eventually win.
