Landwalk
Landwalk is a former evergreen keyword ability on creatures that makes the creature unblockable if the defending player controls at least one land with a certain characteristic.
From the Comprehensive Rules (November 8, 2024—Edge of Eternities)
- 702.14. Landwalk
- 702.14a Landwalk is a generic term that appears within an object’s rules text as “[type]walk,” where [type] is usually a land type, but it can also be the card type land plus any combination of land types, card types, and/or supertypes.
- 702.14b Landwalk is an evasion ability.
- 702.14c A creature with landwalk can’t be blocked as long as the defending player controls at least one land with the specified land type (as in “islandwalk”), with the specified type or supertype (as in “artifact landwalk”), without the specified type or supertype (as in “nonbasic landwalk”), or with both the specified type or supertype and the specified subtype (as in “snow swampwalk”). (See rule 509, “Declare Blockers Step.”)
- 702.14d Landwalk abilities don’t “cancel” one another.
Example: If a player controls a snow Forest, that player can’t block an attacking creature with snow forestwalk even if they also control a creature with snow forestwalk.
- 702.14e Multiple instances of the same kind of landwalk on the same creature are redundant.

History
Landwalk was introduced in Alpha.[2] The keyword always appeared in conjunction with a subtype or supertype to denote the appropriate characteristic, and in most cases did not actually appear as “Landwalk”, but instead “Islandwalk”, “Desertwalk”, “Snow Forestwalk” and so on. “Denimwalk” was used in Unglued. Exceptions to the rule were “Nonbasic landwalk” (Dryad Sophisticate, Trailblazer’s Boots), “Legendary landwalk” (Livonya Silone, Ayumi, the Last Visitor), and “Snow landwalk” (Zombie Musher).
Landwalk in practice
Landwalk is just another means of turning your creatures unblockable, although its a more native keyword to the card inherit design than actually granting this effect into your creatures.
