Tutelage of the Dead

At the beginning of each end step, if a creature
dealt damage this turn died, put that card onto
the battlefield under your control. Sacrifice it
when you lose control of Tutelage of the Dead.
{1}{b}{b}: Tutelage of the Dead deals 1 damage to
target creature.
Failure should be our teacher, not our undertaker.
Failure is delay, not defeat. It is a temporary detour,
not a dead end.
