Borrowing 100,000 Arrows

Card draw priced against your opponent's board state, which makes this one of the rare blue refills whose ceiling you do not fully control. The text translates the Three Kingdoms straw-boat ploy directly: turn the enemy's own committed forces into your gain. The condition is the entire calculus. Against a defensive opponent who keeps blockers back, the spell draws little or nothing; against a creature deck that has tapped its mana dorks, fired off activated abilities, or simply swung wide the turn before, it can crack open a fistful of cards for three mana. That asymmetry is what separates it from a flat draw spell: you are not paying for a fixed number, you are paying for a snapshot of how overcommitted the other side already is. The wrinkle is that it is a sorcery, so it reads the board only on your own turn, after the opponent's attacks and activations have resolved and their permanents are still tapped from the previous round. You cannot reach into their attack step to punish a fresh swing; you cash in on the residue of one. That timing constraint is the real tax on the effect, and it pushes the card toward decks that can survive a turn and collect the rent afterward. It threatens nothing on its own, and a board of untapped permanents shuts it off entirely, but as a draw spell tuned to an opponent's overextension it occupies a corner of blue's design space that flat cantrips rarely visit.
