Benthic Criminologists (MKM)

Creature — Merfolk Wizard

Whenever this creature enters or attacks, you may sacrifice an artifact. If you do, draw a card.

Solid card draw engine for artifact-heavy blue decks. Benthic Criminologists rewards you for running sacrifice outlets and artifact synergies, triggering twice per turn cycle (entry and attack) to generate consistent card advantage. Works well in Pioneer and Modern artifact strategies, though the five-mana cost means it needs a supporting cast of cheap artifacts to justify the slot—it's not a standalone engine but a strong payoff in the right shell.
