This artifact card from the Magic: The Gathering trading card game is a staple in the game's history due to its efficient mana production.

The Mana Vault functions as a powerful acceleration tool. It costs one generic mana to cast and has a mana value of one. Unlike many artifacts, it does not untap during its controller's untap step. Instead, the card has a built-in upkeep cost: at the beginning of your upkeep, you may pay four generic mana to untap it. If you choose not to pay this cost, the artifact remains tapped.

A significant risk accompanies this power. At the beginning of your draw step, if the Mana Vault is tapped, it deals one damage to you. This creates a strategic decision point for players balancing resource generation against life total management. The card allows the addition of three colorless mana when tapped, providing a substantial boost to mana availability in a single turn.
