Perimeter Patrol

A green common built to reward artifact density it never contributes to itself. The 3/3 body starts at a fair defensive rate, and every artifact that resolves under your control afterward pumps the power a point higher, so a fast permanent-churning deck turns each deployment into another point on the attack. That structure makes it a curve-topper for an aggressive artifact shell rather than a standalone beater: it wants Treasure tokens, cheap equipment, and artifact creatures arriving on the same turn to convert incremental deployment into a swing that outsizes a three-drop slot. The trigger cares about any artifact entering under your control, not just casts, which quietly folds token generation and recursion into the same growth engine. Green is not the color that usually gets the artifact-matters payoff (that ground has historically belonged to blue and red), so the design reads as a deliberate handing of the archetype's ground-pounder role to the color that already fields the biggest early bodies. Absent that support, it is a defensive creature with a dormant trigger; the ceiling only exists where artifacts are a resource being spent every turn.
