Equivalent cards to “Clear the Stage” (black, removal, can have an upside) include:
- “Soul Shatter” (each opp. sacrifices a big creature or planeswalker)
- “Defile” (decent single-target removal, scales with swamps)
- “Snuff Out” (free removal if you control a swamp)
- “Malicious Affliction” (removal with a bonus if a creature died this turn)
Reason: All are black instant creature removal spells with possible upside or added value.
