Everything Under the Moon

I know that tarot usually aren't for Yes/No answers, but if someone needs such an answer, which spread or spreads you would suggest that you have tried? I have tried two so far and they aren't quite good (I mean they did not answer correctly) so any suggestions?

1. Develop relationship with the deck
2. Develop relationship with the spirit in your presence that you are interrogating.

Some spirits may know some things, but not everything.
If chaos in room or deck corrupted answer goes rogue.
If you asking silly things you already know they make fun of you.

Good in hours of Jupiter or Moon but avoid hours of Saturn.

Personally I'm using Doreen Virtue's deck of Magical Unicorns. No I'm not joking.
Answers are not 100% but sometimes they are quite clear.

3. Send my regards to your country

You can cast two cards, accordingly:

- yes/no
- past/future
- up/down

Not right/wrong, good/bad, innocent/guilty... tarot, especially, wouldn't just look at that. It's not a judge.

Interesting suggestions...thank you!
