Gaseous Form

The pure-pillow design, rendered without a single hedge. Damage prevention in both directions turns the enchanted creature into a wall on both sides of combat: it cannot be killed by the attacker it chump-blocks forever, and it cannot pressure anything itself. Both clauses are load-bearing. Cast on your own creature, it buys infinite turns against a single threat (an early answer to fatties in an era when removal was scarce and ground stalls decided games); cast on an opponent's creature, it neuters their best attacker without killing it, which mattered in a design culture that treated "destroy" as the premium effect and "neutralize" as the budget alternative. The aura tax is the catch and always has been: three mana and a card to shut off one creature is a rate that ages poorly the moment the format speeds up or the opponent draws a second threat. Later prevention-based auras (Pacifism, Arrest, Faith's Fetters) kept the neutralize-without-killing idea and dropped the self-targeting use case, because the dual-direction clause reads more elegant than it plays. What this card preserves is the original shape: a blue answer to combat that refuses to interact with the stack, refuses to generate tempo, and asks only that the creature stop mattering. A philosophy piece more than a playable, and worth reading as such.
