It's a hard question.
We played 2 games raspi vs pandora. After it we agreed to replace pandora with lilith, in this case i have much more chance.
Focus on the following things:
Rasputina has counter spell (you lose every built in suit).
She can cast through any forzen hart modell within 10".
Rasputina has sub zero, it ends your activation if she has a tome in the def total and you made dmg through a Ml attack.
How to win?
Try to choose schemes where you need to put markers far away from the most important point in the strategy.
Rasputina is really slow, Wk 3, Cg -.
Use lure and push, if the distance between raspi and her models is higher than 10" she can't use ice mirror/shattered mirror.
Don't stand next to each other, or base contact with any of her minions. Blast dmg, paralyze in btb.
Her every cast is projectile, so try to engage as much model as you can.
If you can engage rasputina she can't do too much thing, and disengage with Df 4 is not so easy
Maybe you should forget sorrows, poltergeist, insidous madness, Ca actions make full dmg on incorporeal models.
The pounce of kade can be a good thing against sub zero.
Heavy hitters also works well.
Kill minions ASAP.
And be ready to loose, it will be a hard game for you what is not so enjoyable.
BTW GL And if have any question feel free to ask!
