Silent Screamer

Painborn (Each 1 life you pay while casting this
pays for {1}. It enters the battlefield with a -1/-1 counter on it for each 1 life paid this way.)
Whenever a creature dies, you may put a -1/-1 counter on Silent Screamer.
Counterflux 1 - {1}{b} (Move one counter from this creature onto another target creature.)
Its nightmarish sound rots your existence.
