Blood Dancer Kera

Whenever Blood Dancer Kera deals damage to
another creature, put a blood counter on it. If a
creature with a blood counter on it would die,
instead exile it with a blood counter on it. Blood
Dancer Kera gets +1/+0 for each creature on the
battlefield or in exile with a blood counter on it.
{u}{b}{r}: This creature becomes a copy of target creature on the battlefield or in exile with a blood counter on it, except it still has all of Blood
Dancer Kera's abilities.
