Golgari Gardens leans on artifacts like Ichor Wellspring and removal like Cast Down and Snuff Out to grind, so Cast into the Fire's artifact-exile mode disrupts their card-draw engine while its damage mode cleans up small threats or Plant tokens. Relic of Progenitus denies value from their graveyard-based cards and can preempt Troll of Khazad-dum-style resilience. Inventor's Axe is a liability here since the creatures it equips die easily to their efficient black removal suite (Cast Down, Snuff Out, Unmake), so we trim it along with excess Chain Lightning for more resilient, proactive disruption.
