I have a friend who's really into tarot cards; I figured she could teach me.Problem is she's really not into Homestuck so I worried this would come off as super lame to her. Oh well.

I actually have a template thing that really clearly explains how to use the tarot cards and the proper layout that came with my first deck. If you want I can give you a picture, it's handy to have for clarification. 

For actual card meanings, you'd want a book with definitions or a good website. Whatever is more convenient.
