Enchantment â Saga
(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I, II â€” Create two 0/1 black Cleric creature tokens.
III â€” Create a 6/6 black Demon creature token with flying, trample, and "At the beginning of your upkeep, sacrifice another creature. If you can't, this creature deals 6 damage to you."

Once the number of lore counters on a Saga is greater than or equal to the greatest number among its chapter abilitiesâ€”in the Dominaria set, this is always threeâ€”the Sagaâ€™s controller sacrifices it as soon as its chapter ability has left the stack, most likely by resolving or being countered. This state-based action doesnâ€™t use the stack.
Once a chapter ability has triggered, the ability on the stack wonâ€™t be affected if the Saga gains or loses counters, or if it leaves the battlefield.
If multiple chapter abilities trigger at the same time, their controller puts them on the stack in any order. If any of them require targets, those targets are chosen as you put the abilities on the stack, before any of those abilities resolve.
If counters are removed from a Saga, the appropriate chapter abilities will trigger again when the Saga receives lore counters. Removing lore counters wonâ€™t cause a previous chapter ability to trigger.
Each symbol on the left of a Sagaâ€™s text box represents a chapter ability. A chapter ability is a triggered ability that triggers when a lore counter that is put on the Saga causes the number of lore counters on the Saga to become equal to or greater than the abilityâ€™s chapter number. Chapter abilities are put onto the stack and may be responded to.
As a Saga enters the battlefield, its controller puts a lore counter on it. As your precombat main phase begins (immediately after your draw step), you put another lore counter on each Saga you control. Putting a lore counter on a Saga in either of these ways doesnâ€™t use the stack.
A chapter ability doesnâ€™t trigger if a lore counter is put on a Saga that already had a number of lore counters greater than or equal to that chapterâ€™s number. For example, the third lore counter put on a Saga causes the III chapter ability to trigger, but I and II wonâ€™t trigger again.
