Nature's Wrath
A taxation enchantment aimed at two entire colors at once, built in the era when hate meant a color rather than a card. The symmetry is technically real and practically a lie: a mono-green pilot pays the upkeep, touches neither blue nor black, and watches opponents grind their own boards down every time a relevant permanent enters. The sacrifice is the load-bearing detail people misread. The triggered player chooses what to sacrifice, and it only has to match by type or color, not be the permanent that just arrived. That turns the clause into a recurring tax on a blue-black resource economy rather than a hard lock: an opponent can land a key threat and feed an older, already-spent Island or Swamp to the trigger, protecting the new piece while still bleeding the manabase. Over enough turns it strips both colors' lands and permanents down, but it punishes the resource base more reliably than any single card. The upkeep clause keeps it from being a free roll; a green mana every turn means the controller has to stay ahead enough to fund it, and the enchantment self-destructs the instant that pressure lapses. It reads now as an artifact of a retired design philosophy, one where sideboard answers were color-coded weapons aimed at whole halves of the color pie rather than surgical responses to a specific strategy.
