Founding the Third Path
Read ahead was the mechanic that finally let a Saga begin where you needed it to, and this is the card that most cleanly exploits the choice, because its three chapters do genuinely different jobs and the right entry point depends entirely on what your hand and graveyard already hold. Enter on I when a cheap instant or sorcery is worth casting free, and the Saga stays on the battlefield to advance through II and III on later turns. Enter on II to feed a graveyard, then let III arrive next turn as recursion. Enter on III only when there is already a spell sitting there worth copying, because III sacrifices the Saga the moment it resolves: that entry is the one-way door, the version where you take the last effect and leave the earlier chapters behind. The choice stays honest because skipped chapters never trigger, so starting deep trades the ramp-up for immediacy and forfeits everything before it. What makes the shell tick is that all three chapters serve a spells-matter deck from a different angle: I is free tempo capped at mana value 1 or 2 to hold the ceiling on cantrips and cheap interaction, II is self-mill fuel, and III is unrestricted recursion, copying and recasting any instant or sorcery a filled graveyard can offer, however expensive. The narrow cost on the free cast and the open one on the copy are the same card looking in two directions: cheap on the way in, greedy on the way out.
