Inquisitor Eisenhorn

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 "{2}, Sacrifice this token: Draw a card.")
