Sporoloth Ancient

Fungal Bloom

Phyrexian Altar

Primal Vigor

Lae'zel, Vlaakith's Champion

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 clever loop turns the natural growth of your fungi into an endless engine of sacrifice. Sporoloth Ancient grants your creatures the ability to harvest their own spore counters to spawn Saprolings, and with Lae'zel, Vlaakith's Champion and Primal Vigor amplifying your counter generation, every investment yields an overwhelming surplus. You use Fungal Bloom to quickly replenish those counters, while Phyrexian Altar immediately recycles the resulting Saprolings into the exact green mana needed to keep the cycle spinning forever.
