Call of the Ring

The Ring-tempting mechanic gives you the same escalating buff sequence most cards hand out for free, but where those treat the temptation as the whole reward, this one attaches a price and a payoff to the choice itself. It turns each act of naming a Ring-bearer into a repeatable draw, charging two life for the card. The subtlety is in what the trigger keys off: not the upkeep temptation, but the moment you actually choose a creature as your Ring-bearer. You need a creature on the battlefield to make that choice, so this is not a draw engine that runs on empty; it rewards a board that keeps at least one body around to carry the Ring. That ties the card-advantage to board presence rather than decoupling it, which distinguishes it from the pay-life-for-cards lineage that runs through Necropotence, Dark Confidant, and the Phyrexian Arena tradition, all of which draw regardless of what you control. What it shares with that family is the life-as-mana logic; what it adds is that the Ring's accumulating abilities ride along on the same choice at no extra cost, so the life you spend advances a second, independent threat you were building anyway. The payment is optional and gates the draw, which keeps the clock honest: at a low total you can decline the card and still take the combat buffs. Both engines require you to keep a creature in play to feed them.
