Whenever you cast a noncreature spell, investigate. Then put a Doom counter on Rogier.

If Rogier has three or more Doom counters on it, it gets -1/-1 and is a black Horror in addition to its other colors and types.

If Rogier is a horror, Clues you control have "Sacrifice this artifact: Draw 2 cards."

At the beggining of your end step, if Rogier has six or more Doom counters on it, sacrifice it.
