Sporoloth Ancient

Fungal Bloom

Phyrexian Altar

Vorinclex, Monstrous Raider

Primal Vigor

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 engine relies on a clever compounding loop fueled by Vorinclex, Monstrous Raider and Primal Vigor working together to generate infinite sacrifices. When you use Fungal Bloom to place spore counters on a creature, Vorinclex's replacement effect doubles them, allowing Sporoloth Ancient to immediately fund its own ability. Removing those counters creates Saprolings, which Primal Vigor then doubles to yield two tokens per activation. Finally, feeding those tokens into Phyrexian Altar generates the exact amount of green mana needed to pay for Fungal Bloom again, locking in an endless loop of death and rebirth.
