Rulings
- If you have a face-up Flip Effect monster, you can activate "Desert Sunlight", and chain "Book of Moon", another Desert Sunlight, and another Book of Moon. When the chain resolves, you will flip the monster down, then up, then down, then back up. The Flip Effect activates twice, and they wait to create a new chain after the current one resolves. For example, if the Flip Effect monster is "Morphing Jar", its effect will activate twice in a chain, as Chain Link 1 and Chain Link 2, they resolve in reverse order, and both players will discard and draw 5 cards, then discard and draw 5 cards again.
