Samurai are too expensive in 10T, I can't see paying another 1SS to Enthrall them into a Zoraida crew is really worth it. I'd rather go with a Convict Gunslinger, Hans or McTavish to give me extra shooting.
The voodoo doll and the burning condition is nasty, and you can do it easily with Zoraida's Hex bag as well as taking Iggy.
Generally if I'm using voodoo doll/nurse combo then I prefer to use the paralyze trigger on take your meds. If not using the nurse, then I summon the voodoo doll and then attack it with Bad Juju and hit his paralyze trigger on it. You get the double whammy of paralyzed and damage on your sewn fate target.
Personally, I generally favour the primordial magic as my totem. I like the card draw it gives and it's ability to count as a scheme marker can be very useful in some schemes (plant explosives or spring the trap for example). If the PM is used up, the I might consider the Voodoo Doll but with the way I like to play the voodoo doll is too costly in AP to make it worthwhile.
