I run her and I like her. She is a bit of a build-around-me card in that you have to take care of picking enough blue permanents - especially those with double blue costs - if you want to turn her into a 5/5. The scrying and making one or two of your dudes unblockable is just good enough to warrant her maindeck inclusion though, so that she isn't a dead pick if you end up with too few blue permanents.
We are still playing her here as well. I actually really like her. She sorta creates a deck herself (though really its along with Master) and always provides some good value.
