Condemnremoval$0.22One-mana white instant that answers an attacking or blocking creature and can be very efficient in combat. It is cheaper than Chastise but serves a similar defensive removal role.
Deflecting Palmremoval$4.29A reactive combat trick that punishes a large attacking creature or combat damage source without targeting destruction. It fills a similar role of stopping an attack and swinging life totals in your favor.
Settle the Wreckageremoval$4.61Exiles attacking creatures at instant speed and is a powerful white combat answer. It is broader than Chastise, trading single-target removal for a mass effect.
Oblivion Ringremoval$0.21A flexible white removal spell that can answer creatures and many other permanents. It is slower and less combat-specific, but fills a similar catch-all removal slot.
Banishing Lightremoval$0.12Similar to Oblivion Ring, it exiles a nonland permanent and can serve as broad white removal. It is sorcery-speed and more versatile than Chastise.
Swords to Plowsharesremoval$8.48The premier white creature removal spell, answering any creature at instant speed. It is much cheaper and more efficient, but the life gain mirrors Chastise's life swing.
Path to Exileremoval$14.67A highly efficient instant-speed creature answer that exiles the threat outright. It is cheaper than Chastise and often functions as the best white removal upgrade.
Austere Commandremoval$1.56A flexible white sweeper that can remove creatures while sparing some of your own board. It is much broader than Chastise, but it serves the same defensive control purpose.
