Artifact Creature - Juggernaut 5/3, 4 (4) Juggernaut attacks each turn if able.
Juggernaut can't be blocked by Walls. Built with neither a way to steer nor a way to stop, the juggernauts were simply aimed at an enemy's best defenses and told to charge.
Illus. Arnie Swekel
10/4/2004: An effect that states "Enchanted creature can only be blocked by Walls" will make the Juggernaut unblockable. The "can only be blocked by walls" effect doesn't override the text on the Juggernaut's ability.
10/4/2004: There is no penalty if for some reason the Juggernaut can't attack, but if it can attack you must do so.
