Zumi, the Temple Advocate

At the beginning of your upkeep, create a 1/1
black Rat creature token.
Whenever a black creature you control dies, you
may pay {b}. If you do, each opponent discards a
card and you draw a card.
"For centuries, the bells of the Nakusai Temple were
like a chilling grudge. Now I know why."
- Umta, the supreme monk of the Kashi.
