Fool's Tome

A draw engine bolted to a self-imposed discipline: it only turns on when your hand is empty, which inverts the usual relationship between card advantage and tempo. Most card-draw artifacts of its era simply paid mana for cards and rewarded hoarding; this one punishes it. The activation gate forces you to spend down to zero before it pays anything back, so the design rewards an aggressive, low-curve deck that wants to dump its hand and refuel from the top rather than a controlling one that sits behind a fistful of answers. That empty-hand clause is the price that makes four-to-cast-then-two-to-activate honest: a Jayemdae Tome that drew on demand would simply be too efficient, so the restriction does the balancing work that rate alone could not. It also creates a real sequencing puzzle, since drawing a card the turn you activate it locks you out of activating again until you have emptied your hand once more. The result is a value piece that asks you to play fast and stay lean rather than turtle up, an unusual ask for a colorless artifact and the reason it reads strangely against the grindier draw engines it superficially resembles.
