Manifold KeyutilityBudget$1.46A direct functional upgrade in many artifact-based decks, since it can untap artifacts and also gives another utility mode. It fills the same role of turning tapping artifacts into repeated value.Magewright's Stoneutility$9.08This serves the same untap-engine role, though it works on creatures rather than artifacts. It is commonly used in decks that want repeatable tap abilities.Puppet StringsutilityBudget$1.14Like Voltaic Key, it repeatedly untaps permanents for mana investment, but it can target creatures as well as artifacts. It is slower, but the effect overlaps as a reusable untap tool.Staff of Dominationutility$10.26A classic combo utility artifact that includes an untap ability among several activated modes. It performs a similar role as a reusable engine piece, though at a higher cost and with more flexibility.Thousand-Year Elixirutility$14.81This is a close analog for enabling tap abilities by untapping creatures, and it also lets those creatures act immediately. While it does not hit artifacts, it fills the same tempo/engine role.Unwinding Clockutility$21.01This untaps your artifacts every turn and can function as a powerful repeatable engine enabler. It is not activated like Voltaic Key, but it serves the same core purpose of reusing artifacts.Corridor MonitorutilityBudget$0.14This creature can untap an artifact, creature, or land on entry, making it useful in artifact combo lines. It is less repeatable than Voltaic Key, but overlaps in combo utility.Clock of Omensutility$6.14A major artifact combo piece that untaps artifacts by tapping two artifacts, enabling repeated value from tapped permanents. It occupies a similar support role in artifact-heavy decks.
