Sporoloth Ancient

Fungal Bloom

Phyrexian Altar

Pir, Imaginative Rascal

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Activate Fungal Bloom by paying , putting two spore counters on a Fungus you control.
3. Activate a Fungus by removing two spore counters from it, creating two 1/1 Saproling creature tokens.
4. Activate Phyrexian Altar twice by sacrificing two Saprolings, adding .
5. Repeat from step 2.

This ingenious loop turns a modest garden of fungi into an infinite engine by heavily amplifying every step of the process. Pir, Imaginative Rascal acts as a vital multiplier from the command zone, ensuring that Fungal Bloom places an extra spore counter whenever it adds them to a Fungus like Sporoloth Ancient. Meanwhile, Kaya, Geist Hunter utilizes her −2 ability to double the output of those activated abilities, turning your counter-removal into an avalanche of token generation. Finally, Phyrexian Altar is the beating heart that recycles those freshly spawned Saprolings back into the green mana required to fuel Fungal Bloom all over again, generating infinite sacrifice and death triggers without breaking a sweat.
