Buy sideboard on ManapoolMono Green Landfall has almost no blue or red permanents, so Terminal Criticism is dead weight here - skip it. Instead, lean on unconditional removal: Maelstrom Pulse cleanly answers Mossborn Hydra or Earthbender Ascension regardless of counters. Duress is weak since their deck is almost entirely creatures and lands with few relevant noncreature targets, so trim a copy or two for proactive removal. Keep Requiting Hex and Shoot the Sheriff in to handle their small creatures, and prioritize racing their landfall payoffs before they double up counters.
Terminal Criticism is excellent here. Their blue creatures like Floodpits Drowner, Spyglass Siren, and Enduring Curiosity are all fine targets. Kaito, Bane of Nightmares is only a creature on his controller's turn, and he has hexproof then, so Terminal Criticism can't touch him as a 3/4 Ninja. Hold it for when he sits as a blue planeswalker on your turn. Dimir Midrange's hand disruption and card advantage engines (Enduring Curiosity) make Intimidation Tactics clunky against a grindy deck. Their best threat, Kaito, is a planeswalker and can't be picked by Tactics, so trim it. Ral Zarek adds another discard effect and a way to rebuy your cheap creatures, which helps in a grindy matchup where they trade removal like Requiting Hex, Bitter Triumph, and Shoot the Sheriff for your threats. Keep Duress in to strip We Say Thee Nay! or Bitter Triumph before they can interact with your threats.
This is a mirror-ish midrange grind against BRG, so Maelstrom Pulse is great for permanently answering The Sackville-Bagginses or Umbral Collar Zealot. Qarsi Revenant's flying, deathtouch, and lifelink body is hard for their ground-based removal suite to profitably trade with and helps stabilize the race. Intimidation Tactics is weaker here since their best cards (Lively Dirge, Obsessive Pursuit) aren't artifacts or creatures worth exiling early, so trim it. Swapping Deathcap Glade for the extra Overgrown Tomb-style fixing isn't needed; instead cut one copy for a land already castable off existing mana since we need a card to pair with the land cut - keep mana base intact by not over-trimming lands elsewhere.
