Mono-Green Landfall ramps into big bodies like Mossborn Hydra and Mightform Harmonizer that easily outsize Burst Lightning and dodge much of Stingerquill Charm's 3 damage mode. Bitter Triumph destroys any creature or planeswalker outright regardless of size, making it a cleaner answer to their threats. Thought-Stalker Warlock adds another cheap discard-attached body to disrupt their ramp spells like Earthbender Ascension or Shared Roots before they resolve. Keep Burst Lightning in minimally since it still answers Llanowar Elves and Icetill Explorer, but trim the rest to upgrade removal quality against their larger creatures.

Dimir Midrange runs plenty of noncreature interaction and card advantage (Kaito, We Say Thee Nay!, and a suite of removal spells) that Duress can strip before it comes online. Duress can't take creatures like Enduring Curiosity, so Thought-Stalker Warlock helps here: if they lost life this turn it can take any nonland card, and otherwise it still forces a discard, all on a menace body that's hard for their small Spyglass Siren-style blockers to stop. Burst Lightning is weak here since it can't target Kaito while he's a hexproof 3/4 on their turn, and it doesn't profitably answer Floodpits Drowner's stun ability. Flamecache Gecko's 2/2 body dies to much of their removal suite. Prioritize proactive hand disruption to stay ahead of their card advantage engines.

This is a grindy mirror-ish BRG matchup full of efficient creatures and removal (Requiting Hex, The Misty Mountains Cold), so we want our own high-impact threats and unconditional removal. Bitter Triumph kills anything regardless of size, which is important against Smaug the Magnificent and The Sackville-Bagginses. Laughing Jasper Flint is a strong top-end threat that generates card advantage every turn and dodges their Requiting Hex (mana value 3). Flamecache Gecko and Hired Claw are our weakest bodies here since the opponent has plenty of 1-2 toughness removal and blockers to neutralize them early.
