I use three because that is all I have right now, but if I had another box of them I'd probably run five in 50ss games. I prefer Pandora's passive playstyle. That is the whole reason to pick her. If you want face beaters go with Lilith and her Nephilim. Pandora is about subtly and passive aggressive play. I've tried using Baby Kade and a Teddy in most of my Pandora lists, but without fail they die by, at most, turn 3. They have yet to kill enough to justify their cost. I just played a game against a Shen Long crew and the second turn he killed both Teddy and Kade with the Lone Swordsman without taking a single wound in return, but then I killed five of his models in the next turn and another in the fourth turn then Shen Long. ALL using three Sorrows and Pandora.
