My characters don't have stands. I just drew what I would IMAGINE my protagonist's stand to be.
His ability is to affect paths of probability, causing events to more often than not turn out for the better for his user. In theory, the user could make a fast, easy fortune by playing slot machines and roulette, which are entirely luck-based. But it wouldn't help so much with skill-based gambling, like poker.
It doesn't have much direct fighting power. But it can temporarily bestow a bit of power directly into its user, making them harder, better, faster, and stronger! At most, pro athlete levels, not "Star Platinum" levels. But when this enhancement is in effect, it the good luck power is disabled.
Once ascended though... its "requiem" ability is "One More Time" which doesn't stop or erase time, but turns it back for some seconds, with the only the user still having memory of what happened in those seconds, allowing them to react accordingly.
