This clever loop transforms a humble garden of fungi into an endless engine of life and sacrifice, fueled entirely by Loading Zone doubling your counter placement and Elspeth, Storm Slayer doubling your token creation. While Fungal Bloom pumps the necessary spore counters onto your creatures—greatly assisted by Sporoloth Ancient granting the ability to harvest those counters—Phyrexian Altar readily converts the resulting Saproling tokens back into the green mana required to keep the cycle spinning.
