Sporoloth Ancient + Fungal Bloom + Phyrexian Altar + Winding Constrictor + Mondrak, Glory Dominus

Sporoloth Ancient

Fungal Bloom

Phyrexian Altar

Winding Constrictor

Mondrak, Glory Dominus

How it works

1. Activate Fungal Bloom by paying , putting two spore counters on a Fungus you control.
2. Activate a Fungus by removing two spore counters from it, creating two 1/1 Saproling creature tokens.
3. Activate Phyrexian Altar twice by sacrificing two Saprolings, adding .
4. Repeat.

This lively cycle turns simple fungal growth into an engine for infinite sacrifice and token generation, legal in Commander, Legacy, Oathbreaker, and Vintage. The machinery starts with Fungal Bloom acting as the mana sink, whose investment of green mana is supercharged by Winding Constrictor to flood your board with extra spore counters. From there, Sporoloth Ancient grants your Fungi the ability to cash in those counters for Saproling tokens, while Mondrak, Glory Dominus doubles that token output to ensure your numbers explode. Finally, sacrificing those doubled tokens to Phyrexian Altar feeds the very mana needed to keep Fungal Bloom pumping out more counters, completing a self-sustaining loop of endless sacrifices and triggers.
