Origin of the Avengers

Sagas usually spend their three chapters escalating a single narrative; this one is engineered as a self-contained aggro engine wearing the Saga frame. Chapter one is a low-cost dig that smooths the draw toward the small Heroes the rest of the enchantment wants to find. Chapter two is the pivot, and its cleverness is a fail-safe: it puts a Hero of mana value three or less from hand onto the battlefield, saving you the mana of casting it, but if you have nothing to deploy it refunds the chapter as a card instead. That clause is what keeps the design from stranding an aggressive deck a turn behind, because a dead middle chapter is exactly the failure mode that punishes tempo Sagas. Note the timing: cast on curve, chapter two resolves the following turn, so a three-cost Hero lands on turn three rather than ahead of schedule; the discount is mana saved, not turns skipped. Chapter three then anthems the whole board, rewarding the wide, cheap creatures the first two chapters were assembling. The mana-value-three-or-less clamp is the discipline tying the whole thing together: it points the free deploy at the same small bodies the anthem most wants to pump, so the card selects its own targets, drops one for free, and then buffs everything you control, all across three turns from a two-mana investment. It builds its own payoff rather than telling a story.
