Culling Dais

Sacrifice outlets that bank their fodder for later are rare, and this one holds value in escrow rather than spending it on the spot: each creature fed in becomes a charge counter, redeemable later as a card whenever the board has nothing left to offer. The split is what gives it teeth. The valve side is cheap (just the tap plus a creature), but the tap is also the constraint: one creature per untap step, so this is a patient sink, not an emergency button. You cannot dump a doomed board into it in response to a wrath; you feed it one body at a time, turn after turn, building the stockpile while the creatures are dying for other reasons anyway. The cash-out carries the real design tension, all of it in the timing: because sacrificing the artifact is part of that cost, removal aimed at it can be answered by activating in response, so one mana held open turns a would-be blowout into your refuel. The question then is whether to cash out now for a thin handful or let counters accrue across more turns toward a fatter draw. Where a one-shot draw effect demands creatures and a spell committed in the same turn, this decouples them: the counters pile up across many untaps, and you pull the trigger only when the threat arrives. It rewards engines already built to spit out fodder, with a floor of a slow draw outlet and a ceiling of a fat refuel once the counters have had time to grow.
