I tried it in Delver lists, but you need the creature to die during your turn and after they see bone picker, they don't wait until your turn to do it. No, you need to turn the Bone Picker on yourself.
It's not slotted in to traditional nic fit. It's a nic fit shell with a build-around concept. It's a more aggressive build. It stops all early tempo beaters as well as the combo creatures. Can even kill Emmy as long as you get a fast draw and have 7 permanents, which isn't unreasonable in a list such as this.
