Visualisation is good all-around, but very different from Luck. In fact, I think in most cases when you have Visualisation, you won't need to waste a use of Luck. What does the character do besides rolling the Gambling skill? (Also, you might have enough time to use Visualisation, as it requires a minute before a roll.)

Visualisation is actually very good for various mechanics, hackers, craftsmen etc.
