This loop operates as an engine of relentless recycling, anchored by Slimefoot and Squee acting as both a recurring threat and a token producer. With Pitiless Plunderer quietly turning every death into a mana-generating Treasure, you have the financial engine needed to fund recurring graveyard returns, while Shilgengar, Sire of Famine provides crucial sacrifice outlets and Blood token generation to keep the momentum going. Even though Embalmer's Tools doesn't feature directly in the basic activation loop, its static discount on graveyard activations acts as an invaluable enabler that can help grease the gears if mana gets tight. Together, these pieces weave an inescapable loop that turns a pile of fallen creatures into an endless cascade of mana, tokens, and triggers.
