Jack-o'-Lantern

The trick to this little artifact is that it never actually asks you to spend a card. It replaces itself in the graveyard-hate slot: a colorless one-drop that sits until you want it, then sacrifices for a targeted exile and a fresh draw, turning the disruption into net-neutral card flow rather than the card-negative tax most graveyard answers charge. That alone would make it a clean cog. What extends its life is the second ability, which lets the artifact cash itself out of the graveyard for one mana of any color once it has already done its job on the battlefield. So the same object contributes twice on two separate axes: once as flexible graveyard interaction with cantrip attached, once as a mana filter that fixes a stray color after it's dead. The design belongs to a small family of artifacts built to earn their inclusion no matter the game state, where the floor is "cycles for a card" and the ceiling is "answers a threat and smooths your mana." The exile clause on the first ability reads "up to one target," so it stays castable even when there's nothing worth hitting, keeping the draw available as pure velocity. It is a utility piece, not a bomb, but it is the sort of utility that asks nothing of the deck around it and quietly gives back on both ends.
