I think Chandra is way over priced at the moment. She should see play but really all she is a copy machine. The rest of her modes are only corner case relevant.

I don't think Skinshifter is a playable card, but I talk about my opinion about it in my next article. However, I didn't think about its applications in control. That could be where it actually sees play. I still stand by on my assessment of it though. It's one or two tweaks away from playability IMHO.
