The mono-blue draw payoff that scales with your own land count, priced so it only pays off in a deck that has committed hard to Islands. Five mana buys a variable haul: draw one for each Island, then hand back two. That discard is the balancing clause. On a two-Island board it is a net loss, a genuine punishment for casting it early or off-plan; on a heavily blue manabase it becomes a refuel that can rebuild an empty hand while filtering the two worst cards you drew into it. The design lineage runs through the "reward for stacking basics" school, where cards read your manabase as more than a cost and the incentive is to skew toward one basic type harder than clean fixing would normally allow. What distinguishes this one is that it turns the discard from pure downside into a graveyard tool: you choose which two cards leave, which matters when the two you shed are reanimation or flashback fuel rather than dead weight. Cast at instant speed on a full board, it is a one-card engine that empties your library into your hand; cast under duress, it is an awkward compromise between the cards you need and the two the spell demands you pitch.
