Plain Walker

Three flavors of "walk" stacked onto a single 2/3 Kithkin Rogue, each a different pun on the same word. Plainswalk is the load-bearing one: unblockability against any player who controls a Plains, an evasion keyword as old as the game itself and about as reliable in a format where white lands are ubiquitous. Then "planeswalkerwalk" makes the pun literal, extending that same can't-be-blocked clause to any defending player fielding a planeswalker. And the combat trigger caps it off by literally walking the party to the next plane in a Planechase game. The escalation is the design: landwalk, planeswalker-walk, and a Planechase walk, each reading as a straight-faced rules ability that just happens to be the same joke told three ways. The Planechase clause is functional only inside the format it references, and that constraint is exactly what keeps the gag honest: nothing here is trying to be good, every clause commits to being a different species of "walk," and the card never breaks character to justify itself. A novelty that rewards reading each ability line slowly enough to catch the next groan coming.
