Mono Green Landfall wants to chain fetch-lands into Earthbender Ascension and Mightform Harmonizer triggers, snowballing power quickly, so removal that answers their best threat is key. Erode and Sheltered by Ghosts let us proactively remove Mightform Harmonizer, while Erode can also target an earthbent land creature before it doubles in power off landfall, keeping their board from running away from us. We trim our own slower cards (Ouroboroid, Multiversal Passage) since this race is won by disrupting their engine pieces rather than out-grinding them.

Dimir Excruciator leans on discard (Duress, Deceit) and efficient removal (Bitter Triumph, Requiting Hex) to control the board before landing Doomsday Excruciator as a card-advantage finisher, so we want to keep pressuring with creatures rather than durdle. Rest in Peace shuts off any Superior Spider-Man copy targets and denies them late-game graveyard value, while Soul-Guide Lantern is a cheap proactive graveyard answer that also cracks for a card when flooded. Cut the slower Multiversal Passage and Ouroboroid, since this matchup rewards curving out with efficient threats over slower options against a deck full of one-for-one removal.

Azorius Tempo leans on evasive threats like Aang, Swift Savior and Aven Interrupter backed by cheap counterspells and removal (Get Lost, No More Lies, Avatar's Wrath), so we want efficient answers to their key flyers rather than mana sinks that do nothing under pressure. Erode and Sheltered by Ghosts both handle their evasive threats outright and dodge their countermagic suite by being cheap, low-commitment answers. Trimming Ouroboroid and Multiversal Passage keeps our curve tight so we can keep applying pressure while removing their best blockers or attackers as needed.
