Okina, Baleful Ronin

Protection from Tarnished
When Okina enters the battlefield, create a
legendary red Equipment artifact named Rivers
of Blood with "Equipped creature gets +1/+0
and has {t}: This creature deals damage equal to
its power to any target" and equip {r}{r}. Attach
it to Okina.
Whenever a creature dealt damage by Okina dies,
draw a card and lose 1 life.
