Putting this out there just in case someone's interested.
Barely even a spread, it's so simple. It's worked well for me though.
1. 'Who is speaking?' (it's best if this card is read intuitively; it's meant to give you hints about your guide's characteristics and how they communicate)
2, 3, 4. The message (you can pull as many or as few cards as you like; have spread positions or not; have a question or not; everything is up to you!)
You can see my readings with it in the Messages from your Spirit Guide
thread. (I've been bad and haven't caught up with the readings like I said I would; shh.)
