Cemetery Tampering

Hideaway usually promises a payoff and asks you to unlock it once, whenever a condition happens to trigger. This one flips the transaction: the exiled card is not gated behind a single moment but behind a threshold you build toward on your own clock, milling yourself three cards every upkeep until the graveyard reaches twenty. That reframes self-mill from a resource that fuels graveyard synergies into a countdown mechanism, a way to measure how many turns you have left before the free spell arrives from exile. The design tension is real: milling three a turn from an empty graveyard is slow, and the payoff arrives only after your graveyard holds twenty or more cards, so the card wants a deck already comfortable filling its graveyard. The hidden card is chosen from the top five when the enchantment enters, before you know what the game will need, which turns the whole arrangement into a gamble made early and cashed late. Whatever gets tucked away has to be worth playing for free several turns from now, not right now, and that delay is the price of skipping the mana cost entirely.
