Tidecloack Ransackers

Flash
When Tidecloack Ransackers enters the
battlefield, put a Bleed counter on target
creature an opponent controls. (Bleed counters
give +0/-1.)
Whenever a creature an opponent controls with
a Bleed counter dies, create a token copy of Tidecloack Ransackers under your control,
except it doesn't have this ability. This ability triggers only once each turn.
