Thallid Omnivore turns every Saproling sacrifice into a 4/3 trampling threat that gains you life — the on-board pressure is real and the engine is self-contained. Four mana for that text is the right price, and in Slimefoot, the Stowaway decks it's an auto-include.

Slimefoot, the Stowaway
Slimefoot, the Stowaway generates Saprolings and drains opponents when they die, so Thallid Omnivore slots directly into that loop — sacrifice a Saproling, trigger Slimefoot, grow the Omnivore, gain life, repeat.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| standard | not legal |
| vintage | legal |
| pauper | legal |
| oathbreaker | legal |
Commander is where Thallid Omnivore actually does something — token-sacrifice loops are endemic to the format, and a recursive life-gain threat that scales with your board is legitimately useful in Golgari and Jund shells. In Pauper it's legal but competes in a much tighter metagame where a 4/3 for four with no immediate board impact is slow. Legacy, Modern, and Pioneer have it legal on paper, but constructed formats don't want a four-mana vanilla-adjacent creature when faster, more disruptive options exist at every turn. Stick to Commander and Pauper Cube if you're looking for a home.

Price Context
Current price
$0.27 bulk tier
At $0.27, Thallid Omnivore is pure bulk — pick it up without thinking. Bulk fungus cards don't spike unless a new Saproling commander drives demand, so expect this price to stay flat.
