Benthic Behemoth is a 7/6 islandwalk threat for seven mana — it ends games against blue players but does nothing against everyone else. Too conditional and too expensive for most tables.
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 Behemoth is legal in Commander, Legacy, Vintage, and Oathbreaker, but sees no meaningful play in any of them. In Commander, islandwalk is a narrow evasion type — lethal against one opponent running Islands, irrelevant against the other two. Legacy and Vintage have no interest in a seven-mana vanilla creature. The only home worth considering is a dedicated Merfolk or sea-creature tribal Commander build that also runs Spreading Seas or Aquitect's Will to manufacture islandwalk across the table.

Price Context
Current price
$0.78 bulk tier
At $0.78, Benthic Behemoth is deep bulk — you're paying for cardboard, not power. The price reflects exactly what it is: a niche, conditional beater with no competitive demand keeping it up.
