Activate Wall of Roots by putting two -0/-1 counters on it (due to Pir), adding .
Activate Tayam by paying 3 and removing three counters from creatures you control.
In response to Tayam's ability, activate Ashnod's Altar by sacrificing Wall of Roots, adding .
Resolve Tayam's ability, milling yourself three cards and returning Wall of Roots from your graveyard to the battlefield with two vigilance counters on it due to Tayam and Pir.
Repeat.
This intricate loop is a masterclass in counter manipulation, fueled entirely by the synergy between Tayam, Luminous Enigma and Pir, Imaginative Rascal. Pir ensures that every counter placed—whether it's the -0/-1 counters required to tap Wall of Roots for mana or the vigilance counters that Tayam grants upon reentry—gets amplified, providing the exact fuel needed to fund Tayam's resurrection ability. By sacrificing the Wall to Ashnod's Altar to generate the necessary generic mana for Tayam, you can repeatedly recycle the Wall from the graveyard while milling your entire library in the process.
