White has plenty of ways to double a single enchantment, but very few that treat every enchantment you play as a copyable resource, and that reframing is the whole design point. This is a repeatable enchantment-duplication engine dressed as a Kor Cleric, and it fires on entry rather than on cast, so it copies whatever lands under it: an Aura you attach, a Saga whose chapters you now get twice, a token-making enchantment, even a creature that happens to also be an enchantment. The "only once each turn" clause is the governor that keeps it from spiraling: without it, a single flicker package or a burst of cheap enchantment-creatures would fold the game in on itself. With it, the payoff comes from a steady stream of enchantments over the course of a game rather than one explosive turn, favoring density over a single big trigger. Because the token is a genuine copy, it inherits enters-the-battlefield triggers, which is where the value compounds: doubling a Saga means doubling its chapter abilities, and doubling an Aura means a second attachment target's worth of static effects. The 3/3 body for five is beside the point; you are not paying for the creature, you are paying for a permission slip to run enchantments in pairs.
