Golgari's removal suite (Fatal Push, Abrupt Decay, Go for the Throat) and Sheoldred punish going over the top with one big Craterhoof turn, so trim to two copies and bring in Nylea's Disciple for life gain to blunt Sheoldred's drain and Professor Dellian Fel's drain combo. Reclamation Sage answers Unholy Annex // Ritual Chamber and any artifacts/enchantments they bring in post-board. Note Boseiju, Who Endures is already in our 40 as a land that can Channel to blow up their own problematic permanents, so don't cut it for a land-neutral swap — keep the manabase intact and treat this as a pure spell-for-spell trim.

Izzet Cauldron grinds with card selection and tempo bounce (Get Out, Prismari Charm) rather than hard removal, so resilient bodies that dodge their small burn are key. Elder Gargaroth is excellent here, its 6/6 body survives Fiery Impulse and Prismari Charm's 1 damage mode, and the repeated value (tokens, life, cards) outgrinds their card advantage plan. Keen-Eyed Curator helps fight back against Eddymurk Crab and any graveyard shenanigans while being a reasonably efficient clock. Titan of Industry's artifact/enchantment modes are mostly dead since they run few permanents worth hitting, and Badgermole Cub is lower impact against a deck without much pressure to race.

UBR is a control-combo deck leaning on Fable of the Mirror-Breaker, Indomitable Creativity, and card draw rather than efficient removal, so a resilient threat that survives Fiery Impulse and generates ongoing value like Elder Gargaroth is excellent. Keen-Eyed Curator helps combat their graveyard recursion plans and is a solid clock they have few ways to answer cheaply. Titan of Industry's modes are weaker here since they don't flood artifacts/enchantments worth destroying, and Badgermole Cub's ramp is less necessary against a deck that doesn't pressure us early.
