Bog Raiders

Swampwalk stakes the entire value of this 2/2 on a single yes-or-no question: does the defending player control a Swamp? If yes, it connects every combat; if no, it is a plain body that trades down with anything its size. That binary is the cleanest evasion the game ever shipped: no flying to track, no protection clauses to parse, no triggers on the stack, just a land-type lookup that either switches the attacker on or leaves it inert. The legibility was deliberate. This came out of a starter product aimed at people who had never tapped a land, and an evasion keyword tied to a land type the new player can literally see across the table was exactly the lesson the design wanted: conditional evasion, and the habit of reading the opponent's board before committing to an attack. Landwalk has since aged into a near-dead mechanic for the same reason it made a good teaching tool, because it hands a creature's whole purpose to the opponent's color choice. The arrival of dual lands, fetched basics, and nonbasic-heavy manabases made "controls a Swamp" both more common and less predictable than the original framing assumed, and a keyword that depends on a clean basic-land read does not survive contact with that. It did its job in the box it shipped in; outside that box, it is a lesson in why evasion this conditional rarely earns a slot.
