Wall

Wall is a creature type, usually found on defensive creatures. They represent barriers for attackers ranging from physical objects to intangible forces. Being unable to attack, Walls in general have a higher toughness than power but there are exceptions, like Blistering Barrier. Walls were introduced in Alpha, which featured ten of them in all colors.

Introduction of Defender on Walls
Originally being a Wall implicitly did not allow the creature to attack. This meant that Wall was the only creature type having a specific rule attached to it and this brought additional rule text on cards like or Artificial Evolution, forced to have a specific non-wall condition to avoid to give an unwanted ability (Defender) added to the creature. This was changed with the release of Champions of Kamigawa when the ability Defender was introduced and the creature type Wall was decoupled from it with previously printed Walls getting an errata adding that ability to them. With the exception of creatures with Changeling, no new Walls have been printed without Defender. This change also meant that changing the subtype of a creature to "Wall" no longer stops them from attacking. undefined

Absence of Walls
Walls were removed for a short time after Eighth Edition because in a sense it was hard to fathom how a Wall of Wood which seemed stationary would be able to move to block a creature. From a flavor perspective, a wall is either an artifact or land. That logic kept Walls away for several years, but sentimentality eventually brought them back. Although Walls didn't make much sense creature-wise, they did have an über-logic to them in that they were used as a means to protect the player. This meta-flavor was beloved by enough of R&D that Walls returned. In Tenth Edition, each color, except black, saw a wall being printed. Walls are used much more sparingly now, and Creative tries to keep them from feeling like inanimate objects.

Notable Walls

 * First Legendary Wall Pramikon
 * Illusionary Wall The first Wall to have a power greater than its toughness.
 * Sunscape Familiar A white Wall that was used in various decks to reduce the mana cost of blue and green spells.
 * Tinder Wall A green wall that can be sacrificed to add, thus providing a short term mana boost or acting as a mana battery.
 * Wall of Blossoms A green 0/4 Wall that, when it enters the battlefield, allows its controller to draw a card; this wall saw and still sees regular tournament play.  It was colorshifted to white as Wall of Omens in Rise of the Eldrazi.
 * Wall of Denial</c> A very large Wall that can virtually not be removed due to shroud.
 * Wall of Glare</c> A white 0/5 that can block any number of creatures.
 * Wall of Hope</c> A small but effective barrier for Weenie rush strategies.
 * Wall of Mulch</c> The closest thing to a "Wall Lord," this was the first Wall that rewards players for putting it in a deck with other Walls; while some cards in Rise of the Eldrazi have similar effects, they are dependent on Defenders rather than Walls themselves.
 * Wall of Reverence</c> A very large defensive creature that can also block Flyers and continuously replenishes the life total of its controller.
 * Wall of Roots</c> A green 0/5 Wall which can be shrunk once a turn to add . It is notable because it can immediately add mana as it does not use undefined, therefore also retaining the ability to block, and it can also produce mana in consecutive turns without the necessity of untapping it in between. It is also one of only two cards to use a deprecated counter (in this case, -0/-1) legal in Modern, the other being Lightning Serpent</c> (+1/+0).
