Necromantic Invocation

Return target creature card from your graveyard
to the battlefield. You lose life equal to its
converted mana cost. If that creature card
was a creature card that died this turn, instead
return all creature cards that died this turn to
the battlefield under your control, and you lose
life equal to the total converted mana cost of
all creatures returned this way.

The dead serve no master but the one who raises them.
