Golgari Gardens grinds with efficient removal (Cast Down, Snuff Out) and small value creatures, and Crypt Rats can sweep your board for X damage to everyone including you, so Weather the Storm's life gain helps you race that damage and their incremental drain effects like Tithing Blade. Pyroblast and Dust to Dust are dead here since Golgari has no blue spells and few relevant artifacts (Ichor Wellspring dying is already value-neutral for them, not worth spending removal-shaped cards on). Nyxborn Hydra is removal-vulnerable and Call Damage Control too slow against their efficient removal suite, so trim both for lifegain to survive the grind.
