Unruly Catapult

A wall that pings, and one that fires again every time you throw a spell. The 0/4 body and Defender place it firmly in the durdle category, but the untap trigger recasts what a defensive creature is for: instead of holding the ground and waiting, it converts a spell-heavy hand into repeatable reach. Each instant or sorcery you cast untaps it, so a turn with two or three cheap spells becomes two or three points to the face, all while the wall keeps blocking. This is the pillow-fort-as-clock pattern, where a card that reads purely reactive turns into an inevitability engine given enough cheap spells to feed it. The damage is aimed at each opponent, not any target, which quietly rules it out as a removal outlet and points it squarely at grinding out life totals rather than trading with creatures. There is a real design problem underneath: red spellslinging decks want to keep casting, but their permanents often sit idle between combats. This gives those idle turns a body that both stonewalls the ground and cashes every spell into direct damage, no combat step required.
