This clever loop turns the green mana generated by sacrificing creatures right back into more fuel for the engine. With Puresteel Paladin's metalcraft ability active, Lotus Ring can be equipped for free each time a new token appears, while Nemata, Grove Guardian provides a steady stream of those targets by pumping out Saprolings for {2}{G}. Although the step-by-step trace focuses entirely on the token-and-sac loop, Garna, the Bloodflame is sitting safely in the wings to grant haste and recur fallen creatures if needed, making this a resilient and self-sustaining engine.
