Ayumi, the Last Visitor
The 7/3 body tells you exactly what this is: a beater built to hit hard and fold under any return fire, three toughness that dies to nearly every blocker or burn spell. The evasion clause is where the design gets strange. Landwalk has always been the most conditional keyword in Magic, contingent entirely on what the defending player's manabase happens to contain, and this version narrows the condition to legendary lands specifically: a category thin to the point of being theoretical. The text reads as decorative outside of decks that have arranged for the opponent to control exactly the right land, which inverts how evasion normally functions. Instead of a creature that simply slips past defenders, you get one whose unblockable clause asks you to supply the enabler: hand your opponent a legendary land, or play in a field where they already run one, and only then does the keyword switch on. Strip the landwalk away and five mana buys a glass cannon that swings for damage it cannot reliably push through without your own help. It dates to a stretch when designers were still mapping how granular landwalk could get, threading evasion through ever more specific land subtypes, and Ayumi sits near the narrowest point on that map: a card stranded at the intersection of legendary-matters and landwalk, where two block themes met and produced something almost entirely conditional.
