Jaded Detective

At the beginning of each end step, if two or
more creatures died this turn, investigate. (To investigate, create a colorless Clue artifact token
with "{2}, Sacrifice this artifact: Draw a card.")
Whenever you activate an ability of a Clue you control, if you spent {w} to activate that ability,
put a +1/+1 counter on Jaded Detective. If you
spent {b}, each opponent loses 1 life. (Do both if {w}{b} was spent.)
