Expose the Culprit

Strategy & Gameplay

Expose the Culprit is a versatile instant from Murders at Karlov Manor that serves as both a tactical combat trick and a crucial enabler for disguise-focused strategies. This red one-mana spell offers flexibility through its modal design, allowing you to choose one or both modes depending on your game situation. The first mode turns target face-down creatures face up, providing immediate utility against opponents who are using the disguise mechanic or other face-down strategies to hide threats. The second mode, however, is where this card truly shines for dedicated disguise decks. By exiling any number of face-up creatures you control with disguise, shuffling them into a pile, and cloaking them, you're essentially giving your creatures a fresh start as 2/2 blockers with ward 2, allowing you to turn them face up later for their mana costs when the timing is optimal. This creates significant tempo advantages and enables surprise plays where you suddenly deploy threats your opponent couldn't accurately assess. Expose the Culprit fits perfectly into red-based disguise decks in Standard and Pioneer formats, where the mechanic sees the most support, but its low mana cost and flexibility make it worthy of consideration in any red-heavy limited or constructed format listed in its legality. Players looking to build around the disguise archetype or those seeking efficient interaction should absolutely include copies of this card.
