Temporary Lockdown

In Commander, Temporary Lockdown is one of the cleanest answers to token swarms, treasure spam, and mana-rock acceleration in the format — all three of which run rampant at most tables. It hits Dockside Extortionist, Sol Ring, Arcane Signet, and every 1/1 creature token without touching your four-plus-mana permanents, making it easy to build around asymmetrically. In Modern and Pioneer, it's a sideboard weapon against aggressive one- and two-drop strategies and artifact synergy decks, where wiping the board on turn three can lock an opponent out of their engine entirely. Legacy has faster, more redundant threats, but Temporary Lockdown still sees spot play as a catch-all against small-permanent strategies that dodge traditional wraths. Across all formats, its value scales directly with how well you can protect the enchantment — in blue-white shells with counterspell backup, it often just wins the game.
