Number 2 is a magic I expected to see within Dresden but not covered the almighty Voodoo. Now Voodoo from what me and my friends have tried to figure out is a real head scratcher. Voodoo has heavy influence on your faith and what Loas you believe in which provides your list of powers in a sense. It also offers the temptation of dark magic via voodoo dolls for domination and such. So a simple one but how would you work it? Issue we have is how to tie in a sort of faith power mechanic to leads to you being able to do some funky magic tricks.

I've watched four episode of the series now and I think the round of inaction is probably a good idea, but another idea could be that the skill being borrowed is reduced to mediocre for one round instead. That said, I'll have to watch the rest of the series, see if the moment of confusion reduces/disappears once the characters get used to being sensates.

I saw this power in the Custom Powers master list. It seems perfect for my next character, but I'm worried it might be a little to strong. Has anyone used it in play?

Dream or Reality [-2]
For you the lines between Dream and Reality are blurred, so much so they are almost non-existant. You live just as much in the world of fantasy as you do on planet earth. You are able to bring your control of your Demesne into the mortal world. You are able to shape reality to your whim.
Skills Affected: Discipline
Musts: Demesne
Effects:
Sculpt Reality. You can alter reality as if you were in your personal Demesne, though not as freely as you would be able to in the Nevernever. You can roll Discipline to place scene aspects as normal, and can even use discipline to physically attack using the (now) mutable nature of the zone against your opponents. However, your attacks are all weapon: 0. Any change you make is impermanent, and reverts to its original state at the end of the scene, however, you may spend a fate point to make a change permanent (or more, at the GM's discretion).
Rapid Eye Movement. When you use this power your eyes flicker back and forth as if you were sleeping.
Illiteracy. You are unable to read, it is not because you do not know how, it is just that your brain is unable to correctly identify the symbols on the page. If you somehow loose access to this power, you will be able to read (if you were previously able to).
Improved Sculpting -1. Your attacks are now treated as Weapon: 2.
Powerful Sculpting -1. Your attacks are now treated as Weapon: 4, and any scene aspect you place is automatically made 'Sticky'.

Yea, balance was a concern here.  The other cluster-mate in theory, mentally switches places or is in some sort of very basic autopilot.
Initially it's just accidentally tapping into each others' senses.  As it person A is listening to loud music on her headphones, and person B a continent away thinks his neighbors are playing loud music.  Or seeing a different person in the mirror.  A combat example early is when one of the sensates- a bus driver in Nairobi- is getting attacked in a rural village.  He accidentally calls upon a clustermate, a Chicago cop, who is able to fire a gun with much greater precision than the original sensate.  It's literally only a single action.  Meanwhile, the Nairobi driver briefly sees himself in the Chicago PD station.

While you can't predict exactly what the players will say and do, once you play with them for a while, you'll get a feel for how they approach such things and can plan accordingly. Before the conversation starts, consider what Maeve does want instead of what she doesn't want to reveal. Then come up with a way for her to say the literal truth that leads the players in the direction Maeve wants them to go. Have Maeve steer the conversation, like Aurora does in that book, to lead the players and their characters away from the topic Maeve wants to avoid.
