Founding the Third Path

As 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.

If you cast a card “without paying its mana cost,” you can’t choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those to cast the card.

If the card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

You must pay all costs for the copy of a spell you cast as Founding the Third Path’s last chapter ability resolves. If you choose to cast it, you must cast as the ability resolves. You can’t wait and cast it at a later time.
