2 rulings from Wizards of the Coast
- 9 September 2022If Love Song of Night and Day’s first chapter ability can’t legally target an opponent, or if the ability’s target becomes illegal while the ability is on the stack, you don’t draw any cards.
- 9 September 2022As a Saga with read ahead enters the battlefield, its controller chooses a number from one to that Saga’s greatest chapter number. The Saga enters the battlefield with the chosen number of lore counters. Neither choosing the number nor putting the counters on the Saga use the stack, and neither can be responded to.
