This clever loop turns the graveyard into an endless engine of growth by knitting together type-changing magic and tribal vengeance. With Xenograft declaring "Cleric" as the universal creature type, every permanent you control simultaneously counts as a Cleric, allowing Phantom Train to instantly devour any creature on your board and fuel its own relentless growth. Each time you sacrifice a creature to the Train, Rotlung Reanimator notices a Cleric dying and immediately resurrects your ranks by spitting out a fresh 2/2 Zombie token, ready to be sacrificed right back to the cause.
