The Mirari Conjecture
Two turns of visible setup buy one turn where every instant and sorcery you cast comes twice. Chapters one and two hand back a single spell each, an instant then a sorcery, so the finale arrives with a restocked hand and a copy clause on everything you play through the rest of that turn, with fresh targets on each copy. Doubling a burn spell, a card-draw spell, or a tutor while retargeting the copy is the kind of turn that ends games outright. The pacing is the tax. Lore counters accrue on a fixed schedule (one as it enters, one after each of your draw steps), so absent outside help the payoff cannot be accelerated and the opponent watches the crescendo approach from two turns out, with time to hold up interaction for the turn it will matter. The copy effect also expires at cleanup, so the deck has to be built to unload the entire finale in a single turn rather than bank the ability for later. That is precisely the tension the Saga template exists to arbitrate: a high ceiling gated behind an unhurried, publicly visible countdown. Where most spell-recursion in blue lives on a single trigger, here recursion becomes a scheduled sequence, and the design leans into the wait rather than apologizing for it.
