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 a 1/1 Squirrel and a 1/1 Saproling creature token.
3. Activate Phyrexian Altar twice by sacrificing the Squirrel and Saproling, adding .
4. Repeat.

This loop transforms the natural growth of your fungi into a relentless engine of sacrifice, supercharged by Pir, Imaginative Rascal to turn every single spore counter placement into an overwhelming surplus. With Sporoloth Ancient providing the native counter generation and Fungal Bloom offering a mana-sink to manually seed your fungi, Pir ensures you're always getting bonus counters to feed the engine. Chatterfang, Squirrel General doubles every Saproling token created into a bonus army of Squirrels, and finally, Phyrexian Altar harvests those freshly minted tokens for the exact green mana needed to pay for Fungal Bloom's activation and keep the cycle spinning infinitely.
