Wall

A wall is usually a defensive creature that, by default, either has the rule text "walls can't attack", or after an errata, has defender. This assumption was removed in Champions of Kamigawa when defender was added. Now, any new wall does not automatically have defender, it must say so on the card. Being a defensive creature, walls in general have a higher toughness then power but there are exceptions like Blistering Barrier.

Walls were removed for a short time after 8th 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. In 10th Edition each color, except black, saw a wall being printed. No explanation was given as to why walls came back to print.

Notable walls

• Wall of Blossoms — A green 0/4 Wall that, when it comes into play, allows its controller to draw a card; this wall saw, and, in formats which it is legal in, sees, play in some tournament green decks.
• Wall of Mulch — The closest thing to a "Wall Lord," this is the only wall that rewards players for putting it in a deck with other Walls.
