Benthic Anomaly
Creature — Eldrazi Serpent
Devoid (This card has no color.)
When you cast this spell, for each opponent, choose a creature that player controls. Create a token that's a copy of one of those creatures, except its power is equal to the total power of those creatures, its toughness is equal to the total toughness of those creatures, and it's a colorless Eldrazi creature.

Benthic Anomaly lands as a massive Kraken body that blankets your board in hexproof — that protection is the whole reason to run it. The cost is nine mana and a sorcery-speed cast, so outside of Ulalek, Fused Atrocity shells that cheat it into play for free, it needs a ramp plan behind it.
Best Commanders
Commanders with the highest synergy
Ulalek, Fused Atrocity
Ulalek, Fused Atrocity copies every triggered ability from Eldrazi you cast, and Benthic Anomaly's enters-the-battlefield hexproof blanket triggers on cast — meaning your entire board gets protected repeatedly as the engine fires.
Marvo, Deep Operative
Marvo, Deep Operative cares about casting spells with the highest mana value among cards surveilled, and Benthic Anomaly's nine-mana ceiling makes it the ideal top-end threat to flip off the top and deploy for free.
Kiora, Sovereign of the Deep
Kiora, Sovereign of the Deep lets you cascade into Krakens and Leviathans whenever a creature of that type enters, and Benthic Anomaly qualifies on both counts — it enters as a Kraken and immediately shields whatever else Kiora cascades into alongside it.
Gogo, Master of Mimicry
Gogo, Master of Mimicry copies creatures it transforms into, and Benthic Anomaly's enters-the-battlefield trigger means a copy of it re-grants hexproof to the whole board each time Gogo mimics it.
Runo Stromkirk
Runo Stromkirk flips by showing a creature with mana value six or greater, and Benthic Anomaly at nine is a reliable flip condition that also gives the Krakens and Serpents Runo generates a blanket of protection once it resolves.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Benthic Anomaly's home is Commander, where nine mana is reachable and a one-shot board-wide hexproof effect against three opponents justifies the investment. In Legacy and Vintage it's technically legal but entirely unplayable — nine mana does nothing competitive formats can't answer at instant speed before it resolves. Oathbreaker shares Commander's multiplayer dynamic and could support it in a high-CMC shell, though the tighter 60-card constraint makes the payoff thinner.

Price Context
Current price
$1.09 cheap tier
At $1.09, Benthic Anomaly sits squarely in budget territory for a card with a genuine niche in Eldrazi and sea-creature Commander builds. That price is stable — it's not a bulk throw-in, but demand is narrow enough that it won't spike unless a new Eldrazi or Kraken commander pushes it into mainstream rotation.
