BRG's game plan leans on cheap value creatures such as Callous Inspector, Biotech Specialist, and Rottenmouth Viper, so Day of Judgment resets the board when they overextend. Astelli Reclaimer provides a resilient flying threat and can return a fallen permanent from your graveyard to keep pace on value. Rest in Peace cuts off Greedy Freebooter's Treasure generation and any graveyard-based recursion while exiling their yard outright on entry. Braided Net's tap effect is too passive against a deck that generates card advantage through sacrifice and mana ramp, and Candy Trail doesn't do enough to affect the board; the second Torpor Orb is redundant since your maindeck copy already covers their key enter-the-battlefield triggers.

Izzet Spellementals leans on cheap cantrips like Opt and Sleight of Hand alongside payoffs like Hearth Elemental and Eddymurk Crab that scale off their graveyard, so Negate is well-positioned against their many noncreature spells including Prismari Charm and Traumatic Critique. Rest in Peace is particularly strong here since it exiles their graveyard, directly hurting Hearth Elemental's cost reduction and shutting down any flashback-style value. Candy Trail and a Braided Net are too passive to keep pace with their tempo plan, so trim them for proactive answers. Keep your artifact core intact to pressure them while they're tapped out on cantrips.

Mono-Green Landfall wants to flood the board with mana dorks and landfall creatures like Sazh's Chocobo, Mossborn Hydra, and Mightform Harmonizer, so Day of Judgment as a Sorcery board wipe is excellent at resetting their board state. Astelli Reclaimer is a large 5/4 flyer that outclasses their ground creatures and can rebuy a permanent from the graveyard, giving good value after a wipe. Perilous Snare comes out because single-target exile is inefficient against their go-wide plan, and one-for-one removal falls behind their card advantage engines like Icetill Explorer and Glimpse the Core. Riverchurn Monument adds incidental mill pressure and a repeatable mana sink, replacing a couple copies of Candy Trail whose card selection is less impactful once the plan shifts toward sweeping and stabilizing. Keep the core artifact engine (Cryogen Relic, The Mind Stone, Simulacrum Synthesizer, United Battlefront) intact since it still generates value and blockers between wipes.
