Jecht, Reluctant Guardian // Braska's Final Aeon

The whole design gates a punishing engine behind a single combat condition: this 4/3 with menace has to connect with a player before it becomes anything, and connecting is the only way through. If it trades with a blocker, it dies without transforming; the trigger keys off combat damage to a player, so the front face is not a body you throw away but a delivery vehicle you have to land. Menace is there to raise the odds of that hit against a developed board. Once the damage goes through, you may exile it and return it as a Saga that reads like a slow execution: two chapters of forced discard that also refill your hand, then a chapter that strips two creatures from each opponent. Because the returned permanent is a fresh object with its own lore counters, the flip is a genuine card-type change rather than a value bump, and the Saga advances on the draw step regardless of what happens in combat afterward: blockers cannot race a timer. The transformed side is an Enchantment Creature that keeps its menace, so it can keep pressuring the board while the chapters tick over, but the arc is one-directional. The Saga sacrifices itself after Chapter III; there is no return trigger on the back, so the payoff is a single arc of value, not a loop. The card belongs to the wave of double-faced designs that ask you to earn the powerful half with an attack step instead of paying for it in mana.
