Ancient Carp
A 2/5 with no text is a body and nothing more, and the body is the whole proposition: five toughness that shrugs off the early beats while five mana buys you nothing to do with the turn. This is the vanilla wall in its plainest form, a creature whose only job is to stand in front of attackers and not die to a 4/4. There is no evasion, no ability, no late-game pivot from defense into offense; the design asks the surrounding cards to supply the plan while this one holds the line. Big-toughness commons like this exist as a floor for slower environments, a guaranteed blocker that trades up against aggression and buys the turns a controlling deck needs to find its real threats. The trade it offers is honest: a defensive anchor for a slot, with no pretense of being anything else. Where the cheap creatures hit hard and games run long, a fish that survives most of what comes at it for the first several turns does quiet work. Where they don't, it has nothing to offer, and the stat line never tries to suggest otherwise.
