I've just started playing her as well, and there is just so many means things you can do with her.
I almost always include The First mate, and Bad Juju has done great work as well (despite me being a bit sceptic to him at a glance) and both McTavish and Spawn Mama seems competent for their costs. You rarely go wrong with a silurid or two, and so far I've brought one Will-o-the-Wisp in her games as well. That leaves some flexibility, but I fins myself considering a lot of her keyword in certain matchups. What she seems to lack is armoured beaters, but a decent cache can help you go far enough.
So far she have played decently into most strats, although corrupted idols and plant explosives seem to fit her extra well. In Idols you can use her obey trigger to walk an enemy up to the idol and suffer three damage to throw it far onto their half and in explosives I've tried to advance with a decently protected swpampfiend (such as juju or a stealthed model) early so I could obey my opponents to drop their bombs on their table half (extra insult to injury of you get enscorcel to charge a friendly model afterwards). Another decent strategy in most early games is to just walk+charge backwards with the opponents most lucratice beater to deny them that movement and maybe put some damage out. And in the end game you have so many options to score your points and deny points to your opponent, it's can feel rather silly...
The voodoo doll feel like a special mini game in itself. My go-to tactic is to torment it with the above mentioned Wisp. Hitting it once with any crow gives distracted+1, stunned and slow to the linked model (which can be an enemy master) and efficiently shuts it down. More occasionaly I've stabbed it a little bit with Zoraida, but that has mostly been cases where I really needed that one damage that is hard to avoid. Bonus points for the doll is that you can kill it (with actions or it's own bonus action) and get scrap markers for the second point of dig their graves or gator snacks for McTavish. The first one is doable but corner case while the second one can be rather consistent!
