Kick in the Door
One red mana buys three effects where an older pump spell bought one: a permanent +1/+1 counter, haste to pull a fresh body into the red zone a turn early, and a dungeon step. The "can't be blocked by Walls" rider is pure door-kicking flavor, a jab at a defensive shell that almost never fields the Walls it names; treat it as a joke printed on the front of the card, not a clause to build around. What earns the slot is venture. Because this is a sorcery and can only fire on your own turn anyway, it was never going to sit in hand as an ambush; that frees it to lean into going early and on curve, where the counter sticks and the haste has a new creature to enable. Bolting a dungeon advance onto the pump means the card is rarely dead weight: when the combat math is irrelevant, you have still banked progress toward a completion, and unlike a burn-priced bonus that evaporates at end of turn, the counter stays on the board. That is the interesting inversion for a spell of this shape. It quietly folds a repeatable, deck-wide subgame into effects cheap enough to run without ever caring whether a given fight broke your way: a small card carrying a large idea, priced so the venture is worth the mana even on the turns the swing does nothing.
