Forever Young

What separates this from every other black recursion sorcery is where it puts the cards back: not into your hand, but on top of your library, in an order you choose. That distinction is the entire point. Returning a stack of creatures to hand refills your board immediately but strips your library of future draws; sending them to the top instead converts your graveyard into scripted turns while replacing itself with the cantrip. You are not casting these creatures now, you are guaranteeing your next several draws are exactly the threats you want, then digging one card deeper to keep the sequence moving. The "any number" clause is what gives it reach: one target is a modest tutor-plus-draw, five targets rebuilds an entire topdeck sequence to grind out a long game. The cost of that flexibility is tempo and timing. It does nothing to the current board, it locks in draws you cannot reshuffle away if the game state shifts, and it rewards a graveyard already stocked with creatures worth drawing in a particular order. This is recursion for attrition, a black effect that treats the graveyard as a deck to be reloaded rather than a pile to be raided.
