Replicate was a Storm-era Guildpact mechanic bolted onto instants and sorceries: pay the cost again, get another copy. Grafting it onto Sagas is a stranger, slower idea, because a Saga is not a one-and-done effect but a scripted multi-chapter sequence that unspools over your next several main phases. Copying one does not just double an effect; it doubles a timeline. Each replicate copy enters as its own token Saga, each ticking through its chapters on its own clock, so the Science Teacher ability turns any Saga you cast into a stack of parallel narrative engines that all resolve their finales on the same turn. The design tension is obvious the moment you look at the cost: replicate here equals the Saga's full mana cost, so the ceiling is only as high as your ramp, and doubling a five-mana Saga asks for ten mana before you see a single extra chapter. That keeps the effect honest against the cheap, punchy Sagas and rewards the top-heavy ones with sprawling payoffs. The Doctor's companion keyword ties it into the two-headed commander structure, where this can sit as the white half of a partnership as well as a standalone general. It is a build-around that only pays off in a deck committed to enchantment-based storytelling, which is a narrow ask, but the payoff (chapter triggers multiplied by however much mana you can pour in) scales further than most doubling effects because it compounds across turns rather than resolving all at once.
