Echoes of Betrayal

When this enters the battlefield, gain control of
target creature until end of turn. Untap that
creature. It gains haste until end of turn.
When you gain control of a creature owned by an
opponent, flip a coin until you lose a flip. For
each flip you won, create a token that's a copy of
that creature. Those tokens gain haste. Exile
them at the beginning of the next end step.
