Cognivore scales directly with instants in all graveyards — in the right game, that's a 10/10 or larger for a manageable blue cost. The catch is it costs 5UU with no evasion baked in, so it needs a graveyard full of instants before it's worth casting.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Cognivore is legal in Commander, Legacy, Vintage, and Oathbreaker — formats where graveyard accumulation is realistic over a long game or across multiple players. In Commander it's at its best: four players means four graveyards counting toward its power, and a mid-to-late-game table will often have 20-plus instants buried collectively. Legacy and Vintage have the raw instant density to make it enormous quickly, but faster, more efficient threats crowd it out of those formats entirely. Oathbreaker mirrors Commander's dynamic on a smaller scale — viable in the right spell-heavy shell, but not a staple.

Price Context
Current price
$0.40 bulk tier
At $0.40, Cognivore is deep bulk — zero barrier to picking up a copy. Demand is narrow enough that the price is unlikely to move unless a high-profile Commander list pushes it, so treat it as a cheap roleplayer, not a spec.
