This is a Polymorph engine wearing an end-step trigger, and the twist is that you supply the fodder yourself. Where the classic version of the effect feeds a token into a random dig, this one asks you to sacrifice a real creature and pays you a look scaled to that creature's mana value: cash in a modest three-drop and you peek at three cards, feed it something expensive and you dig deep enough to reliably surface a payoff. The design converts board presence into card selection, and the sacrificed body's mana value is the currency that buys the depth of the look. That clause is also the constraint: a zero-cost token or a one-mana dork buys almost nothing, so the engine wants genuine board investment as fodder rather than chaff, which flips the usual Polymorph incentive of sacrificing the cheapest possible creature. What keeps it from spiraling is the once-per-turn cadence tied to your own end step, plus the failure state baked into the search: if the top X cards hold no creature, the whole pile goes to the bottom and you have spent a body for nothing. That variance is the price of dropping the payload straight onto the battlefield rather than digging it out of a graveyard. The result is a grinding value loop rather than a combo enabler, one that rewards a deck stacked with high-mana-value creatures worth both sacrificing and hitting, and turns a creature that has already done its job on cast into a fresh look at a bigger one.
