Moonglove Extract

Two damage stored in colorless mana, payable in any deck regardless of color identity: a utilitarian piece of removal built to be a reliable floor rather than a ceiling. The three-mana cost is paid up front, the artifact sits on the battlefield until you need it, and the sacrifice delivers its payload at instant speed to any target. That deferral is the actual value: you commit the mana on a slow turn and hold the spell-on-a-stick until a creature you want dead taps out, a planeswalker drops to two loyalty, or your opponent stabilizes at exactly the wrong life total. As a colorless source of direct damage, it slots into builds that have no other way to point removal at a target, and the sacrifice clause makes it fodder for engines that want artifacts leaving play. What it is not is efficient: two damage for three mana up front is a poor rate by any era's standard, and the card survives in the design vocabulary because flexibility and color independence buy back what the rate gives up. It belongs to the long line of removal-on-a-permanent that lets a deck pre-pay for an answer it does not yet know it needs.
