You may reveal the first card you draw each turn as you draw it. Whenever you reveal an instant or sorcery card this way, create Cherubael, a legendary 4/4 black Demon creature token with flying.
Whenever Inquisitor Eisenhorn deals combat damage to a player, investigate that many times. (Create a Clue token. It's an artifact with ", Sacrifice this token: Draw a card.")
Eisenhorn rewards a high density of instants and sorceries: reveal the top card on your draw step (or via extra-draw effects) and flip a 4/4 flying Demon, Cherubael, into play. Connect with Eisenhorn in combat to investigate for a pile of Clues, refueling your hand and bleeding the table while your spells keep the board under control. You grind value, build a wide Demon-and-Clue engine, and close with evasive beaters or card-advantage-fueled combo.
Maximize cheap cantrips and top-deck manipulation (Brainstorm, Ponder, Sensei's Divining Top, Scroll Rack) so your first draw is almost always a spell. Add repeatable extra-draw engines like Howling Mine effects you control or Teferi's Puzzle Box variants, plus evasion (Whispersilk Cloak, Rogue's Passage) to guarantee Investigate. To spike the power level, lean into an aristocrats payoff package (Blood Artist, Zulaport Cutthroat, Ashnod's Altar) that turns your endless tokens into a kill.
