This clever loop harnesses Vizier of Remedies as a brilliant counter-mitigation engine, changing the `-1/-1` counter that would normally cripple a returning creature into zero counters at all. Because Persistent Constrictor enters the battlefield clean, its persist ability can trigger anew every single time it hits the graveyard. You feed this endless cycle into Thermopod by sacrificing the Constrictor to its ability, generating an infinite supply of red mana and fuel for any death-related triggers you desire.
