Thanks - whiich of the two is best i am not sure to be honest, obviously Sheryl will be more stable ability wise but Scubb can be used all the way up to the round 3. I have found him useful for the low pill fights as you can overpill a little.
God I love Kristin. She is probably the most confusing card in the game. When your opponent gives you a 7/5 Stop All by losing a round, they have to think carefully to either avoid the situation or to figure out how they're going to keep a 7/5 Stop All from ruining their game entirely.
