Hmm, multiple delayed gratification; sort of level-up enchantments. Yeah, I can see it. A bit fiddly to keep track of though, which might be a concern if you've got a lot of them floating around.

>> Saga (At the beginning of your upkeep, activate the next chapter not completed. When you can't, sacrifice this permanent.)

Right now I feel a sorcery with rebound and text that alters what you get on the second casting would be preferable.

I assume you plan to go with even more chapters at higher rarities, but noetheless getting just the first chapter out of the way immediately greatly reduces the complexity of this mechanic.

Also the reminder text should not use the term "activate" which has very specific rules meaning that does not apply here.

EDIT: And since I'm already commenting on the general mechanic, it's also weird that the enchantment usually stays around for a turn after its last chapter is finished. It's additionally weird that there are exceptions to this if the last chapter gets canceled because of a lack of target.

What happens if you cannot utter a verse due to lack of target?

• Do you fail to get the effect but continue otherwise resolving the ability (skipping the verse forever)?
• Do you fail and try again next upkeep?
• Do you fail and end the sequence this there is no "next verse" to follow on "no verse" (which would mean failing even once to find a target keeps the enchantment around)?

I added "up to one" on the second ability.

Okay so, uttering is same as "triggering" it. No target(s) means fizzling. You continue to next verse as normal on next upkeep. I would wager this is how most people would assume it to work. So the first option of your choices if I understand it correctly.

In any case, if all the verses have effects that have no targets or have "up to X" targets this shouldn't be much of an issue.

I did actually consider a version where you "complete" costs for effects, like saccing a creature or returning one from grave to hand. That would have made them more quest -like.

So we all recognize you pioneering Sagas, but it took me until today to realize these also use flavor words ahead of time. It might be, that we could do with more flavor words on Sagas.
