Armored Cancrix

Five toughness for five mana, two power, and nothing below the type line: this is the defensive vanilla creature stripped to its barest form. The number that does the work is the toughness, since five blanks nearly every aggressive early drop and stonewalls most of the midgame attackers a patient blue deck needs to outlast. The two power keeps it from being a pure wall; left unanswered, the crab eventually puts an opponent on a clock, however slow. There is no ability to build around and nothing hidden in the math: a curve-blunter, a body that holds the ground while a better card does the winning. As blue creatures go, that is its own kind of statement. Blue's lower-rarity bodies have rarely been about combat, and a sturdy ground-staller with a real backside is the color leaning into its controlling instincts the only way the commons allow: by refusing to die on the ground until the game tilts toward whoever is content to wait. It delivers exactly what the toughness promises and not one thing more, which is precisely the function it was drawn to serve: buying time rather than spending it.
