Sorry, didn't see you could manually stop the slot reels. However, my point still stands, as you're far more likely to end up with either a null or negative result, which would make this skill particularly finicky in the middle of a fight. Twisted Fate's Pick a Card, on the other hand, grants him a bonus effect no matter what (even if it's not the one the player intended).
