Kellan, Inquisitive Prodigy // Tail the Suspect
The Adventure half is where the design logic hides. Tail the Suspect works like a variant of the ramp effects that fetch a land and draw: it trades the on-cast card into an Investigate token, banking a Clue and an extra land drop before the creature ever arrives. You spend two mana early to smooth your curve, then cast the 3/4 flier later from exile, paying its printed cost when you do. The point is not free value; it is that one deck slot resolves two effects at two different points in the game, the split-card promise made literal.
The creature side reads as narrow (an attack trigger that destroys an artifact does not sound like much) until you notice the conditional: if you controlled the destroyed permanent, you draw. That clause turns the trigger into a repeatable draw engine when pointed at your own disposable artifacts, the Clue you generated on the front half chief among them, or a Treasure or Food you no longer need. The detective who investigates in the early game cracks his own evidence for cards in the late game. Vigilance keeps the body back on defense while it swings to fire the trigger. It is an uncommon case of an Adventure whose two modes are built to feed each other rather than merely coexisting: the Investigate half seeds the artifacts the combat half destroys, closing the loop within a single card.
