Sivriss, Nightmare Speaker

Description

Sivriss, Nightmare Speaker (CLB-393 foil) is a legendary black creature that can be used as a commander and has the Choose a Background ability. It has an activated ability that taps and requires sacrificing another creature or an artifact to mill each opponent and potentially return those milled cards to your hand unless they pay 3 life. As a black commander with reanimation/hand-retrieval upside, it often plays a control or value role in graveyard-focused or sacrifice-themed decks.
