Mana Vault (MPS-17 foil) is a Kaladesh Inventions Masterpiece artifact reprint of the classic mana engine. It taps for three colorless mana but enters a taxing state by not untapping during your untap step and has upkeep options that can untap it or deal you damage. Its role is accelerating early plays at the cost of potential life loss and payment to keep it active, making it a high-impact ramp piece for decks that can manage the drawback.
