Expose the Culprit
Instant
Choose one or both —
• Turn target face-down creature face up.
• Exile any number of face-up creatures you control with disguise in a face-down pile, shuffle that pile, then cloak them. (To cloak a card, put it onto the battlefield face down as a 2/2 creature with ward 
. Turn it face up any time for its mana cost if it's a creature card.)

Expose the Culprit exiles a nonland permanent an opponent controls — hard removal, not a bounce or tuck — at instant speed for two mana. In Kaust, Eyes of the Glade decks it also replaces itself, making it removal that doesn't cost you a card.

Commanders with the highest synergy
Kaust, Eyes of the Glade
Kaust, Eyes of the Glade triggers whenever you cast a spell from somewhere other than your hand, so Expose the Culprit cast off the top or via Kaust's own draw-from-exile effect counts — removal that feeds the engine rather than interrupting it.
Yarus, Roar of the Old Gods
Yarus, Roar of the Old Gods rewards casting spells from exile, and Expose the Culprit is exactly the kind of cheap, instant-speed spell you want available on top of your library — it clears a blocker or a problem permanent without eating a card from hand.

Expose the Culprit is a Commander card almost exclusively — the format's multiplayer politics and slower pace make a two-mana exile that replaces itself genuinely competitive with the format's best removal. In 1v1 formats like Modern, Pioneer, and Legacy, the bar for removal is lower CMC and unconditional targeting, and Expose the Culprit can't clear creatures without a nonland qualifier distinguishing it from staples like Prismatic Ending or Leyline Binding. Standard is the one 1v1 context where it sees fringe play, mostly in decks that want cheap exile effects and don't need to target creatures exclusively. Outside Commander, treat it as a role-player at best.

Price Context
Current price
$0.15 bulk tier
At $0.15, Expose the Culprit is bulk — pick it up without hesitation in any Kaust or Yarus build. Cards at this price point don't hold speculative value, but for a two-mana instant exile with a cantrip upside in the right shell, the entry cost is essentially zero.
