Wall of Pine Needles

A green wall built to outlast aggression rather than simply block it once. The defensive shell pairs a 3/3 body with a regeneration ability that costs a single green mana, so as long as the green keeps flowing it shrugs off combat damage and most early removal that relied on dealing three or less. That is the design logic: a wall's job is to absorb attacks turn after turn, and a body that dies to the first trade is a wall in name only. Regeneration converts the static defense into a renewable resource, taxing the green mana you would otherwise be spending elsewhere but buying time against creature decks that need to break through the ground. The friction is that the ability does nothing on offense; defender locks the body in place, and the regeneration only matters when something is trying to kill it. As a green defensive piece from an era when walls were a real archetype consideration, it represents the school of thought where the early game was about surviving the curve rather than racing it, and a recurring blocker that demands an answer beyond combat was a genuine roadblock to plan around.
