Equivalent cards to “Unmask” in black include:
- “Thoughtseize” — Also discards a card from opponent’s hand.
- “Inquisition of Kozilek” — Similar effect, but with a CMC limit.
- “Duress” — Discards noncreature, nonland cards.
- “Collective Brutality” — Has a discard mode and alternative cost.
Reason: All are black cards that disrupt hands, some with alternate costs.
