Cyclone

Few early cards wear their design intent as openly as this one: a self-escalating tax that ends in a board wipe, with the tension front-loaded into the upkeep step rather than the cast. The first turn costs a single green to keep alive and deals one to everything; the second costs two and deals two; by turn four of its life the controller is paying four green to clear four toughness from every creature and four life from every player, themselves included. The sacrifice clause is the pressure valve: this is not a permanent presence, it is a countdown the controller chooses to extend, and the moment the green stops flowing the enchantment falls off on its own. Symmetry is total. The damage hits each creature and each player, no exceptions for the owner, no protection clause, no scaling that favors the caster. That is the Arabian Nights design vocabulary: high-variance effects priced cheaply at the front and balanced by punishing the person who deployed them. Modern green would not print this ability on green (the mass-damage-to-creatures-and-players shape has long since migrated to red), and would not let the controller decide each turn whether to keep paying. The card is a record of a moment when color identity was looser and when "you also take the damage" was considered a sufficient cost on its own.
