Eloise, Nephalia Sleuth

Two triggers that feed each other, engineered so a single sacrifice engine loops death into cards and cards into graveyard fuel. A creature you control dies, you get a Clue; you crack that Clue (or any token), you surveil, digging toward the next payoff. The clever part is the token clause on the second ability: it reads on any token, not just the Clues the first ability makes, so Treasures, Blood, Servos, and food all trip the surveil trigger. That widens the build far past a straightforward Clue value pile and turns Eloise into a general-purpose token-sacrifice payoff wearing Dimir colors. What keeps it from spiraling on its own is that neither half draws a card outright: the Clue still costs two mana and a sacrifice to convert, and surveil only bins or keeps, never draws, so the engine demands actual sacrifice outlets and mana to close the loop. The design sits at the intersection of two archetypes that rarely overlap: aristocrats, which want creatures dying, and artifact-token value, which wants fodder to sacrifice. Eloise is the bridge, rewarding both the death and the sacrifice as separate events so a board that does both at once compounds. The graveyard-filling surveil is the tell that this was built with reanimation and delirium payoffs in mind, not just raw card advantage.
