What is the relationship (if any) between mystics and Satan?

Well it depends on how you define "mystic" but psychic insights are often provided by demons. Things like transcendental meditation and drug use can open you up to the spirit realm that Satan and other fallen angels inhabit. I firmly believe that the inhabitants of the DMT realm are fallen angels, I believe the "ascended masters" people contact are fallen angels, I believe the "logos" that Terrence McKenna communicated with was a fallen angel (maybe even satan himself), I believe that the spirits shamans communicate with are demons/fallen-angels. I would say most mystics don't believe in satan, but that doesn't change the fact that they are affected by him and may even communicate with him directly. The Bible tells us that Satan masquerades as an "angel of light" so he is able to take on many different forms.

Mystics are wither deluded or straight up con artists, satan is a delusion.

Mystics are willing to talk to Satan.

Intimate.

they both share one thing and that is that they do not exist
