Barrage Ogre

The body is incidental; the activated ability is the whole reason the card exists, and it converts spent artifacts into reach. The trade is the engine: tap and sacrifice an artifact, get two damage anywhere, repeat each turn so long as you keep feeding it. That makes it a sink for cards that have already done their work (a spent equipment, a clue, a treasure, a leftover token) and a way to bleed those resources into a clock or a removal stream. Five mana for a 3/3 is a bad rate on its own, which is the point: the price is paid in the artifacts you no longer need, not in the stat line. It sits in a lineage of creatures that turn permanents into repeatable burn, the artifact-fueled cousin of the sacrifice-and-ping designs that recur across red and black. The tap cost is the real governor here, capping it at one shot per turn cycle and asking the deck to supply a steady drip of fodder rather than dump everything at once. Where artifacts are cheap and plentiful, it quietly becomes a removal piece, a finisher, and a way to push the last points through a stalled board, all from the same square.
