Viscid Lemures

The -to-evade ability is the whole pitch, and it descends from a long line of cheap evasion grants that have always paid the same toll: you trade body size for a clean attack. Here the swampwalk is conditional on the defender controlling a Swamp, which makes the ability a meta-read more than a button. Against another black deck it is a free pass to the face every combat step; against decks with no Swamps it does nothing but shrink the 4/3 into a 3/3 if you misclick. That asymmetry is what dates the design. Landwalk belongs to an older evasion philosophy, one where unblockable was tied to the defender's manabase rather than a universal keyword, and an activated swampwalk grant is that philosophy at its most literal: it punishes mirror matches and folds entirely outside them. Setting the activation at zero is almost a joke at the card's own expense, since the ability can only ever matter when the opponent controls a Swamp, and against everyone else the free activation is a trap that only ever costs you a point of power. As a creature it is a 4/3 with a clause that asks you to know your opponent before you commit; against the right table it is genuinely hard to stop, and against the wrong one it is filler with a button that hurts you to press.
