Vaultwright's Boon
The Key to the Vault from Outlaws of Thunder Junction is a compact engine of card advantage wrapped as a legendary artifact equipment. The Key to the Vault gives you a route to find and cast spells ahead of curve by turning combat damage into library interrogation. Attach it to a evasive attacker and each point of damage becomes a peek at that many cards and a chance to exile a nonland card to cast for free, changing how you sequence attacks and stack your tempo plays.
As a piece of set lore the artifact feels like a lockpick blessed by coastal thieves and frontier artificers. The card rewards careful timing and board planning. It pairs cleanly with one toughness pings and trample triggers, and it creates tension when your opponent must choose whether to block a creature that can turn damage into a free spell. Practical players will use it to convert incremental damage into decisive value.
