Hex Parasiteutility$7.95A black-aligned counter-manipulation tool that can remove counters from any permanent, making it a partial functional match for clearing counters. It is repeatable and much more flexible, though it does not exile tokens.
Soul Divinerutility$2.11Provides ongoing counter removal from artifacts, creatures, enchantments, and planeswalkers you control, echoing the counter-clearing part of Aether Snap. It also draws cards in the right shell, though it only hits your own permanents.
Power Conduitutility$8.70A reusable way to remove counters from your permanents, similar to the counter-removal aspect of Aether Snap. It can transfer those counters rather than wipe the board, so it is more of a utility engine than a reset spell.
Leech BonderutilityBudget$0.39Can move counters around and effectively clear them from a creature by stripping them off and redistributing them. It plays a similar counter-interaction role, though it is creature-based and far less sweeping.
Render Silentremoval$2.10Not a counter-removal spell, but it serves a comparable disruptive control function by stopping a key spell and suppressing follow-up plays. It is a reasonable blue-black style control substitute if you are looking for a similar defensive slot.
Beseech the Mirrorutility$28.36A black value tutor that can find a key answer or combo piece in a similar mana range to Aether Snap. It does not interact with counters or tokens, but it fills a comparable high-impact sorcery slot in black decks.
Ob Nixilis's CrueltyremovalBudget$0.09A strong black removal spell in the same broad mana range that answers a creature efficiently. It does not replicate the counter reset, but it is a functional black control alternative for the same deck slot.
Extinction Eventremoval$0.91Another black sweeper that removes a swath of permanents from the board, giving a similar reset feel to Aether Snap. It does not touch counters or tokens directly, but it is a comparable black control finisher.
