Satsuki, the Living Lore

Sagas run on a fixed clock: a lore counter on entry, another on each of your upkeeps, then sacrifice once the final chapter resolves. This bends that clock in both directions at once. The tap ability drops a lore counter on every Saga you control simultaneously, which is not just acceleration but a way to detonate several final chapters in a single turn, sequencing those closing triggers back to back. That changes what a Saga is worth: payoffs you would normally wait multiple upkeeps for become an activated engine, and the sorcery-speed clause is the only leash keeping it from working as an instant-speed combat blowout. The death trigger closes the loop from the other side. A deck built on churning Sagas burns through them fast, and the modal ability lets you bounce a still-ticking Saga back to hand to reset its chapters, or return a completed one from the graveyard for a second run. Note the asymmetry between the two modes: bouncing an enchantment creature you control only works while it is still on the battlefield, so a Satsuki dying alongside it in a wrath cannot save a permanent that hit the graveyard first; the graveyard-recursion mode is the one that survives a wipe. The tap pushes Sagas toward their conclusions; the death trigger recycles the ones that got there. A three-toughness body meant to be traded still cashes in a chapter's worth of value on its way out. This is the axle a Saga engine turns on: inert without chapters to spin, indispensable once they are there.
