Thallid Soothsayer card art
Thallid Soothsayer turns spare Saprolings into card draw at instant speed — sacrifice an any creature, draw a card, no mana required beyond the initial four to cast it. In Slimefoot, the Stowaway builds especially, it doubles as a sacrifice outlet that triggers Slimefoot while keeping your hand full, and Wedding Ring decks that want cheap repeatable draw on a body will notice it too.

Slimefoot, the Stowaway

Slimefoot, the Stowaway

30.2% of decks · synergy 0.29

Slimefoot, the Stowaway drains opponents whenever a Saproling dies, so Thallid Soothsayer's free sacrifice outlet turns every token into both a card and a drain trigger — it's one of the tightest functional fits in the archetype.

02
The Mycotyrant

The Mycotyrant

15.4% of decks · synergy 0.14

The Mycotyrant grows on each opponent's graveyard trigger and floods the board with Fungus tokens, giving Thallid Soothsayer a constant stream of fodder to convert into cards and keep the engine moving.

Thallid Soothsayer is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but it only sees real play in Commander. The four-mana cost and one-card-per-sacrifice rate are too slow for competitive Constructed formats where dedicated draw spells and faster sacrifice payoffs dominate. In Commander, the repeatable free-activation stands out — most sacrifice outlets either cost mana or don't replace themselves, and Thallid Soothsayer does both on a creature body that survives without needing the stack.

Price Context

Current price

$0.32 bulk tier

At $0.32, Thallid Soothsayer is bulk in every sense — easy to pick up in trade binders or grab as a throw-in. Bulk rares with specific tribal homes tend to stay flat, so there's no reason to expect this to move unless a future Fungus or Saproling commander spikes demand.
