Warded Battlements

Walls are supposed to defend, so a Wall that pushes your attackers forward is working against its own type line, and that contradiction is the whole design. Defender keeps this 0/3 planted at home, contributing nothing to combat math on its own turn except the static +1/+0 it hands to every creature you send in. It is an anthem hiding in a blocker's body: your board gets bigger without the card ever swinging, and the toughness means it survives most of the early attacks it is built to absorb. The trade is stark. You spend a card and a slot on something that can never win a race by itself; the payoff is only as good as the number of attackers standing beside it, which is why the effect scales with a wide board and does nothing with an empty one. That tension (a static combat boost stapled to a body that refuses to enter combat) makes it a go-wide piece dressed as a defensive one, the rare Wall you deploy because you intend to attack, not because you intend to hold the ground.
