best purchase of the event so far ?

As act 2 comes to a close , I thought it would be interesting to hear people opinions on what they feel has been their best premium purchase of the event so far ? I'l admit that I have mostly bought from the mystery box as I was missing Manjula, Boobarella and Sherri and Terri thought I bought Alisson Taylor who isn't a bad buy.

I'm still considering buying Knifey Spooney. I'm sure many have bought more new characters and it's always fun to hear the divided opinions :)
