Deputy of Detention

In Commander, Deputy of Detention pulls weight as a tempo piece that can blank an entire token army or neutralize a problematic permanent in a way that bypasses indestructible. The bounce-back clause is a real liability in a four-player game where opponents have multiple ways to kill your creatures, so builds that can flicker or protect Deputy get the most mileage. In Modern and Pioneer it has seen sideboard play as a catch-all answer in white-blue shells, particularly against token strategies where Path to Exile or Detention Sphere cover single threats. Legacy and Vintage have enough fast interaction that a three-mana 1/3 rarely makes the cut outside fringe brews. Oathbreaker mirrors the Commander dynamic — useful in spell-heavy value shells, fragile without support.
