Meteorite

Two effects that lived in separate cards for years, welded into one artifact: a ping on entry and a rainbow rock. The lineage runs through the mana-fixing artifacts that produce any color plus some incidental extra, but here the extra is aimed rather than automatic. Two damage on arrival clears a mana dork, finishes a planeswalker someone left low, or plinks a face when nothing better presents itself, and once the shot resolves the artifact stays behind as a fixer that keeps paying rent. That pairing explains why it reads as filler and behaves as glue: the removal always has somewhere to point, because the opponent is a legal target when the board offers nothing, and the mana ability earns its keep long after the shot is spent. The cost is where the design stays honest. Paying full price for two damage and a mana rock is not a rate anyone constructs around, but a rock that removes a blocker on the way down is doing two jobs from one card, and the front-loaded tax stops the effect from crowding out sharper removal. Built for decks that want fixing and would happily accept a small tempo swing on top, it charges for both effects precisely because it delivers both.
