Anguished Unmakingremoval$12.94Efficient Esper removal that hits any nonland permanent at instant speed. It is slightly more flexible in that it exiles instead of destroys, but asks for 3 life.
Desparkremoval$1.33Cheap Orzhov removal that answers many problematic permanents, especially high-cost threats. It is narrower than Void Rend because it only hits mana value 4 or greater.
Utter Endremoval$0.28Another instant-speed answer to any nonland permanent in Esper colors. It costs one more mana, but exiles the target instead of destroying it.
Vindicateremoval$0.95Classic multicolor removal that can destroy any permanent, making it very close in function. It is sorcery speed, but the ability to hit lands gives it extra reach.
Generous Giftremoval$1.21Flexible instant-speed removal that destroys any permanent. It gives a 3/3 token in exchange, but otherwise fills a similar universal-answer role.
Bedevilremoval$0.45Solid Rakdos-style permanent removal that can destroy an artifact, creature, or planeswalker. It is narrower than Void Rend, but is comparable in being a flexible instant answer.
Descent into Avernusremoval$14.12Not a direct removal spell, but if you're looking for efficient noncreature permanent interaction in multicolor shells, this is not similar enough; better option is Detention Sphere for permanent-based exile. However, in strict functional terms, Detention Sphere provides repeatable removal of a nonland permanent and related cards.
Detention Sphereremoval$0.32Exiles a nonland permanent and can also catch copies of it, making it a strong enchantment-based answer. It is sorcery-speed and vulnerable to enchantment removal, but serves a similar catch-all role.
