BRG floods the board with mana dorks and small value creatures like Llanowar Elves, Gene Pollinator, and The Sackville-Bagginses, so Deadly Cover-Up stays in as a key sweeper and doesn't need support from narrow single-target removal like Shoot the Sheriff. Strategic Betrayal forces them to sacrifice a creature to exile along with their graveyard, cutting off recursion from Lively Dirge even if they choose which body to give up. Duress strips Witherbloom Charm or a removal spell before it can interact with your own threats. Ghost Vacuum graveyard-hates their Lively Dirge reanimation targets while doubling as a late-game army-in-a-can against their go-wide plan. Deceit and one Bitter Triumph come out since their board is full of small creatures that don't demand a six-mana body or a two-mana instant when cheaper interaction is available.

Izzet Spellementals fills its graveyard with Opt, Sleight of Hand, Flow State and Prismari Charm to cheapen Hearth Elemental and Eddymurk Crab, then uses those Elementals to cut the cost of Sunderflock, which bounces every non-Elemental creature. Requiting Hex has no targets in their 75, since every creature they run has mana value 3 or more, so all four come out along with the sorcery-speed Maelstrom Pulse. Strategic Betrayal is the best card we can bring in: they exile a creature and their entire graveyard, which erases the discount on their next Crab or Hearth Elemental. Intimidation Tactics strips a big Elemental from their hand before it gets cheap, and The End exiles a Crab or Sunderflock at instant speed along with every other copy in their hand and library. Deceit is an Elemental Incarnation, so Sunderflock's bounce doesn't touch it; hold Bitter Triumph and Shoot the Sheriff up for a flashed-in Eddymurk Crab.

Mono-Green Landfall is a creature-based ramp/aggro deck with almost no relevant noncreature permanents, making Duress mostly dead weight against their curve of Llanowar Elves, Icetill Explorer, and Mightform Harmonizer. Qarsi Revenant's flying, deathtouch, and lifelink lets it trade up against their bigger bodies and stabilize the race, while Ghost Vacuum can strip Icetill Explorer or Mole Man, Moloid Master fuel from the graveyard to blunt recursion value. Ancient Vendetta is excellent here, letting us proactively exile all copies of a key landfall payoff like Bristly Bill or Mightform Harmonizer from hand, library, and graveyard. Deadly Cover-Up remains our core sweeper against their wide, low-toughness board, while Requiting Hex offers cheap, efficient single-target removal for their early creatures.
