Grand Insquisitor Leberhart

Eminence - At the beginning of your upkeep,
if Leberhart is in the command zone or on
the battlefield, target opponent chosen at
random becomes a suspect.
At the beginning of your endstep, if no one
is a suspect, add {w}{g} or investigate.
{u/b}: Target human gains skulk until end of
turn, use this only once each turn.
