The Fourth Doctor
Green-blue has flirted with library-peek engines for years: Courser of Kruphix let you replay lands off the deck, Vizier of the Menagerie let you cast creatures for free, Future Sight opened everything up at the cost of hiding your hand. The recurring tension in all of them is that seeing your next card and using it are two separate favors, and most designs grant only one cleanly. This bolts the two together and then narrows the reward to a type the deck already wants to be full of: historic cards, meaning artifacts, legendaries, and Sagas. The result is an engine that runs on the same card quality it enables, since a build stuffed with legendary permanents turns nearly every draw into an extra play off the top. The once-each-turn clamp is the governor: rather than letting the whole library empty in a single burst, it grants one bonus land or spell per turn. Crucially it reads "each turn," not "your turn," so a historic spell with flash can spend the bonus on an opponent's turn, opening a reactive window most engines of this kind never touch. The Food token is pure flavor, a nod to a certain scarf-wearing Time Lord's habit of offering jelly babies; nothing on the card consumes it, so it is upside for whatever else wants artifacts around. Structurally it is a card-advantage engine wearing a 4/4 body: real in combat, but run for the steady, historic-typed selection it grants every turn it survives.
