Land Tax

Catch-up insurance, written before the term existed. The card encodes a structural assumption about Magic that has held for three decades: falling behind on lands is the worst place a fair deck can be, and the player who solves that problem cheaply solves a lot of other problems for free. The conditional trigger is the entire design: it does nothing when you are ahead, and it does everything when you are behind, which means the rate (one white mana for what amounts to a three-card draw plus library thinning, since those basics leave the deck) is balanced by a constraint that punishes the matchups where the effect would be unfair and rewards the ones where it is fair. Note what the trigger does not do: the lands go to hand, not the battlefield, so this is card advantage and deck-smoothing, not ramp; you still have to spend a land drop to deploy what it gives you. White's color-pie identity around lands (fetching basics, taxing nonbasics, punishing greedy manabases) traces a direct line through this enchantment to every catch-up cantrip and basic-tutor effect printed since, but the original remains the cleanest expression of the idea: a single white pip that turns a mana disadvantage into card advantage, and the template every "if an opponent controls more" condition has been measured against.
