Rulings
- You can only activate the ① effect if you already have a "Lightsworn" monster in your GY. However, when choosing a target, you can choose to target the card you discarded, instead.
- If you control multiple "Lightsworn" monsters, their End Phase effects don’t chain to each other (they each activate, one after another).
