Insatiable Souleater is a 3/1 artifact creature that can gain infect by paying Phyrexian red mana — meaning you can pay 2 life instead of mana to make every hit a poison counter. The cost is real: life payments add up fast, and a 3/1 body dies to a stiff breeze.

In Commander, Insatiable Souleater is a niche piece in infect or Phyrexian-themed builds, where the life-payment on infect is subsidized by life-gain engines or high starting totals. Pauper is the format where it sees the most honest use — aggressive infect strategies can activate it repeatedly before opponents stabilize, and the common card pool makes a 3/1 infect body more competitive. In Legacy and Vintage it's outclassed by faster, more resilient infect threats and won't see serious play. Oathbreaker mirrors Commander in that it wants a specific shell to justify the life cost, but 20-life totals make the payment steeper relative to the game clock.

Price Context
Current price
$0.04 bulk tier
At $0.04, Insatiable Souleater is pure bulk — you'll spend more on a sleeve than the card itself. That price is stable because demand is narrow; it won't spike unless infect gets a breakout competitive moment, which isn't on the horizon.
