Dark Magic's Bindings

This Sorcery stays on the battlefield until end of turn, and its abilities can be used more than once,
in any order.
{b}: Target creature gets -1/-1 and is tapped.
{2}{b}: Your opponents can't use any spells this turn.
{4}{b}{b}: Exile target tapped creature, then, search all Libraries for duplicates of that card and exile
them too.
