Needle and Notion
Toxin Analysis is a compact instant that turns a single combat step into an exchange that favors you. Cast it for {1}{B} to grant a creature deathtouch and lifelink until end of turn, letting a modest attacker trade up or a blocker trade down while you recover life. The Investigate trigger also creates a Clue token which can be cashed in later for card advantage, a neat economy play that meshes with graveyard and artifact synergies common to Karlov Manor decks.
Use it in tempo windows where a single removal or a surprise trade seals a board position. The card reads plainly yet offers layered utility: immediate combat relevance and a delayed resource on the stack. In lore terms this is a clinician of secrets, extracting a fatal truth and preserving evidence for those who follow the trail.
