Origin of the Hidden Ones

Sagas usually reward patience, unfolding value across three quiet turns; this one is a windup for a single decisive swing. The chapters read as a compressed aggro arc: four damage to any target to clear a blocker or push reach, then a pair of menace-carrying Assassin tokens, then a chapter that pays off precisely what the second chapter built. Chapter III watches for Assassins you control attacking that turn and answers each declared attacker with another 1/1 that enters tapped and attacking, and it lands on the same turn the Saga leaves. That timing is the whole design. The final chapter is not passive standing value but a demand to commit to combat immediately, and the payoff scales with how wide your board already is rather than how long you wait: only the Assassins that actually declare an attack feed it, so the tokens it spawns arrive as extra damage rather than as fresh triggers, which keeps the closing chapter from spiraling. Most Sagas use their two setup chapters to accrue a resource and their finale to cash it; here the accrual and the cash-out point at the same combat step, so the card wants a board already primed to attack the turn the third chapter fires. The menace stapled to every token is what turns the finale from a token dump into something a defensive board cannot simply chump, since each one-power body demands two blockers to stop.
