Two abilities that quietly want the same opponent: the swampwalk makes it unblockable against black decks, and the death trigger drains them regardless of how it dies. The bundling is the point. Evasion against a Swamp-running opponent means the body gets in for two until they find a way to deal with it, and the moment they do, the dying creature taxes them another two. It is a small reward structure that loads the value into the matchup where the creature is already best, then hands you a consolation drain when removal answers it. The death-trigger half also makes it indifferent to how it dies: chump-attacking, trading in combat, being sacrificed, or eating removal all pay the same two life, which is the kind of "no bad outcome" math that aggressive black decks like in a body this cheap. Landwalk has always been a feast-or-famine keyword, completely live against the right base and a dead word against everything else, and the death drain is the design's hedge against the famine half. None of it adds up to a card that demands an answer, but the construction is honest about what it is: a beater that punishes black mirrors twice over and refuses to die for free.
