Nothing worked...depends on what you were trying to do.
More than 70 percent of the spells on here do not work. They are here to bring traffic to the site so it will gain money for future updates and/or other site subjects.
It is encouraged that you make your own spells, if you are experienced enough.
To get a good idea of magick and how it works, research a few articles on here about magic. Also, to get a good foundation built, I would suggest starting with the basics such as meditation, grounding, centering, energy minipulation and visualization.
Magic is not yours to control. You work with magic. You respect magic.
Any spell that sounds illogical such as shapeshifting, flying, teleportation, any type of kinesis, or anything that changes your dna is anyway is impossible. Keep that in mind when searching for a spell to try out.
