Ancestral Recall

The spell has one of two effects, much like the MTG counterpart. 

Ritual  You set up a complex ritual circle to attempt to gain lost knowledge. You can ask the DM one question that you or one of your past lives (characters) used to know the answer to. If the DM has told you the answer in the past they may repeat that answer.

Tell the Future You pull out a deck of cards and shuffle them, then draw 3. You and/or the DM may interpret their results in any way you wish, perhaps granting inspiration to your DM for future ideas. The DM may just choose to ignore the result and just have your character have a cool roleplay moment. The deck can be tarot cards, MTG cards, just a deck of normal playing cards, or anything the DM deems appropriate.
