Perimeter Captain

Defender decks rarely get a payoff that fires on the one thing every wall does anyway, which is what makes this body the natural anchor for them. Blocking is the verb a defensive shell is built around, and turning each interception into a two-life trickle converts a stall into an attrition engine: the longer the ground gridlock holds, the further ahead the wall player pulls without ever swinging. The 0/4 frame is part of the point too. Four toughness on a one-mana creature shrugs off most early aggression on its own, so the card buys the very board state its own ability rewards. The trigger reads off every defender you control, not just itself, which scales cleanly with a deck stuffed full of walls: each blocker that survives a turn pads the cushion further. The catch is that it does nothing on offense, contributing no clock and leaning on its supporting cast to supply one, whether that is an alternate win condition or a defender that quietly turns the corner. That is the honest tax on a creature whose entire job is to make the defensive plan financially viable: it stabilizes the life total, but the wall it sits behind still has to find a way to actually close.
