Exotic Disease

Domain was the era's reward for the manabase you were probably building anyway: a five-color pile where a fully diverse set of basics was a deckbuilding default rather than a stretch. This is the drain spell tuned to that economy. In a deck that has assembled the full spread of land types it swings ten points of life, enough to close a stalled board or claw back a race in a single sorcery. The catch is structural rather than situational: in a deck that has not reached that ceiling it shrinks toward irrelevance, and unlike a fixed-number drain it offers nothing to a player who cannot pay the diversity tax. That makes it a true archetype payoff rather than a portable staple, the kind of effect whose entire value is dictated by the surrounding land count. The open target widens its use slightly (the life loss can point at any player, for political or threat-assessment reasons as much as for the kill), but the scaling is what the design is selling: a swing that tracks precisely with how committed you were to the multicolor premise. Read it as the closing line at the end of a domain build, not a card that travels.
