This crafty loop is orchestrated by Long Feng, Grand Secretariat, whose vigilant presence turns every casualty into growth by placing a +1/+1 counter whenever a creature or land you control hits the graveyard. We use Pentavus as our engine's heart, spending mana to strip away its counters and spawn delicate Pentavite tokens. Those tokens are immediately fed to Phyrexian Altar to generate the exact mana needed to sustain the process, while their trip to the graveyard triggers Long Feng, Grand Secretariat to replenish Pentavus's lost counter. The result is a seamless cycle that endlessly churns out sacrifice, death, and entry triggers to fuel your victory.
