This clever black-mana loop turns a massive dragon into an endless horde of the undead by feeding the engine's constant cycle of sacrifice and resurrection. With Mass Hysteria granting every creature haste right out of the gate, Ghoulcaller Gisa can immediately chop up Scourge of Nel Toth to flood the board with six 2/2 Zombie tokens, which in turn fuels Pitiless Plunderer to generate crucial Treasure tokens for mana. When you need to recast Scourge of Nel Toth straight from your graveyard to keep the loop going, Gravespawn Sovereign steps in to effortlessly recycle Ghoulcaller Gisa back to the battlefield by tapping five untapped Zombies, ensuring the whole operation can repeat indefinitely.
