Wall of Swords

A pure exercise in early defender design: a flying wall, which sounds like a contradiction until you remember what walls were for. Ground-pounders ran into them; fliers floated over. Wall of Swords answered the second half of the equation by simply being a wall that could block in the air, and the rate (a 3/5 body for four mana, with a toughness line above most early burn) made it a premier defensive answer to evasive creatures in its era. What balances it is the lock between the two keywords: flying does real defensive lifting, but defender means the card can never turn around and become an attacker, so the evasion never threatens to close a game. That trade-off (give a wall the keyword it would normally be exempt from, then bar it from the red zone) is the template every flying wall since has worked from, which keeps the archetype reading as a deliberate design joke rather than a power-level mistake. The card is a relic of when wall-as-creature-type was still a load-bearing mechanical category, before reach got folded into green as the cleaner solution and before defender stopped being a near-universal wall rider. Read it as the original wall philosophy stated plainly: blockers priced on the toughness line, evasion handed out only when it cannot bite back.
