Are there any pagans or witches who shift?

This question has been sort of asked before, but I suppose I’m asking more from a deity work side of things. Of course, if you’ve done a spell for shifting and it helped, feel free to comment!

I’m wondering if anyone has started worshipping/working with deities that have helped you shift. I’m looking into worshipping Merlin, and a deity of death to help.

So main question is: How has paganism/witchcraft helped you on your shifting journey?
