Canyon Wildcat

Whether this Cat's swings actually land is decided by the other player's manabase, not yours. Mountainwalk lets the 2/1 body slide past any defender as long as the defending player keeps a Mountain in play, turning it into a guaranteed two damage a turn against red decks and a fragile vanilla two-drop against everyone else. That conditional evasion is the entire pitch, and it points straight at the era that produced it: a cheap red attacker that walked straight past opposing red defenses was a sharp tool aimed squarely at the mirror. The basic-land evasion keywords all asked the same trade, offering repeatable unblockability gated behind a guess about what the opponent is running. Here the gamble is low-stakes in both directions: when it connects, combat math evaporates, and when it whiffs you have spent two mana on a creature that dies to almost anything. Canyon Wildcat neither pushes the mountainwalk package nor refines it; it delivers the keyword on a body cheap enough that being inert against half the field never costs much.
