Depends on a few things but yes, luck and curses are real. If you charge enough energy, focus, visualize, the spell needs to be a working spell and, of course, you need to believe in magick.
The specific spell I don't know if it will or won't work, but give it a shot. Curses are commonly frowned upon because karma tends to keep things level, and the negative effects felt by the caster is rarely worth it. But its up to the casters morality whether or not what spells they cast. Research magick so you can separate working spells from fake spells, and determine what spells you feel you should and shouldn't cast.
