Custodi Peacekeeper

Most creatures arrive on the battlefield with fixed parameters. This one arrives with one blank that gets filled during the draft itself: the reveal-as-you-draft clause records your pick number in the round, and that noted figure becomes the power ceiling on what the tap ability can hold down. Grab it as your tenth pick of a round and the ability pins any creature with power ten or less; grab it early and the reach is smaller. Because the ability checks the highest number you noted across all your copies named Custodi Peacekeeper, a second copy taken later only raises the ceiling, never lowers it. The 2/3 for you actually cast is almost beside the point. The real object being printed is a rule about how you acquired the card, a design that reaches outside the game state entirely, past the battlefield and into the pre-game procedure, to set its own parameter. It also renders the card functionally inert wherever picks are not being counted: with no round to note, the tapping ability has no number to reference, and the card collapses back into a below-rate cleric. A handful of designs treat the act of drafting as a resource the same way most cards treat mana or life, and this is among the purest of them, because the entire scaling mechanism lives in a step that happens before anyone has cast a spell.
