The problem is that there is no such thing as a Beginner spell. One either knows how to do magic or one does not. And if you do know how to do magic then you can do any possible spell. Part of the issue is the idea that all you have to do to do a spell is to read some words you found on a website, light a candle or two and Voila! Your spells will work. That isn't how magic works at all, and trying it that way will be a disappointment.
If you are serious about learning how to master spellwork, then it's going to take time, study and effort. Here are some books that I'd suggest:
"Before You Cast a Spell" by Carl McColman
"Spells and How They Work" by Janet and Stewart Farrar
"The Veil's Edge" by Willow Polson
"Modern Magick" by Donald Craig
Some spells on here will never work no matter how hard you try. You can't turn yourself into some mythical being or anything other than human. You can't create a dragon egg or a dragon here on the physical plane. Magic can help with some things, but even magic is still bound by the physical laws of the Universe.
