Wheel effects have always been priced as a payoff you build toward: seven mana on Wheel of Fortune, six on Windfall, and a whole tempo shell devoted to making the refill worth the turn. This one inverts the model by charging you incrementally, in the currency your deck is already spending. Every noncreature spell you cast racks up an oil counter, and each counter shaves a mana off the sacrifice cost, so a spell-dense board turns the seven-mana ceiling into something you can pay off in a single burst. The design ties the payoff directly to the plan that would want it: a deck built to cast cheap noncreature spells is exactly the deck that empties its hand fast and needs a reload, and the counters accumulate at the same rate the hand drains. The body earns none of this on its own; it is a one-drop that sits on the table doing bookkeeping until the graph of counters against cards-in-hand crosses. Note the discard-then-draw ordering: you jettison whatever is left before refilling, so the ability rewards you for emptying out first rather than sandbagging cards to lose. What makes it a real engine rather than a novelty is that the sacrifice clears the creature off the board, so it doubles as a way to convert a spent one-drop into four fresh cards once its counting job is done.
