Bog Rats

The single line of text here points a creature at exactly one obstacle: the Wall. That premise only makes sense if you remember the design era it comes from, when Wizards still treated Walls as a recurring defensive archetype worth printing dedicated counterplay for, and the answer was to bolt "can't be blocked by Walls" onto an otherwise blank black one-drop. The flaw is that the card's value sits entirely in the opponent's hands: against any deck without Walls, the text does nothing, and a 1/1 for one black mana with no other utility is the floor for a creature. It is a hyper-narrow hate card wearing a creature's clothes, the kind of conditional answer that reads as clever in the abstract and inert at the table, because the condition it punishes is one almost no opponent presents. The instinct it embodies (printing a specific creature type's natural predator) is one the game largely abandoned once it learned that asymmetric, opponent-dependent abilities produce dead cards more often than tense ones. What endures is the snapshot: a black common that existed mostly to walk past a strategy the game has since stopped building around.
