Hibernation's End

The escalating tutor: a toolbox that climbs the curve as it ages. The cumulative upkeep tax is not a downside grafted onto a value engine here; it is the targeting mechanism. Each age counter both raises the cost and sets the exact mana value of the creature you may fetch, so the first payment pulls a one-drop, the next a two, and so on up the chain. That coupling is the whole design tension: you cannot stay on the cheap, repeatable end without escalating into a creature you may not want, and you cannot reach the haymakers without first having paid for everything beneath them. It reads as a graveyard-free reanimator that builds its own staircase, fetching directly onto the battlefield rather than into hand, which dodges sorcery-speed creature-spell timing and any countermagic aimed at the creatures themselves. The friction lives entirely in the upkeep math: every turn the enchantment survives, it demands more, and the search is exact-cost, so a deck has to be curved around it deliberately, with a creature at each mana value you intend to climb through. That makes it less a value rock and more a clock you set against yourself, paying an increasing toll for an increasingly large body until you either find your finisher or let the whole structure collapse and sacrifice it.
