A few I came up with tonight for a player who wants to play a gambler who is supernaturally lucky.
"Roll the dice". [-1]
You have the uncanny ability to make dice roll the way you want them to or to call out what the dice will roll while they are rolling.
In game this comes out to a 50/50 chance - a 50% probability of success.
"Lucky dodge" [-1]
Once per scene, you may use one fate point to completely dodge any one attack.
"It's all in the cards" [-1]
For some strange reason, when you throw a card, it doesn't behave how cards thrown by other people do. It's rather... lethal. Thrown cards are a +2 weapon each, targeted with weapons or discipline, whichever is highest.
"Time is my friend" [-1]
Whenever you wear a quality watch on your body, your amazing luck influences the world around you to the extent that attacks tend to find your watches instead of you.
This power gives you a natural armor:2 for every watch you have on your person.
The number of watches you have on you is determined by a new stress track governed by your resources, to a maximum of 4.
You can buy more watches (clear the track) when thematically appropriate.
*Note, whenever you have more than two watches on you, this gives you the aspect, "WTF is up with all the watches?"
