Dimir Excruciator leans on discard (Duress), countermagic (Spell Snare, Theorix Charm), removal (Strategic Betrayal, Bitter Triumph, Requiting Hex), and eventually a board wipe (Deadly Cover-Up), so Deep-Cavern Bat is premium: it proactively strips their disruption or wipe before they can use it and gives you a flying lifelink body. Cathar Commando can destroy Overlord of the Balemurk, an enchantment creature, and its flash lets it dodge sorcery-speed removal. Kutzil's Flanker's flash lets it dodge sorcery-speed sweepers like Deadly Cover-Up while giving flexible upside (life gain/scry or graveyard hate against their Superior Spider-Man). Goldmeadow Nomad, Resolute Reinforcements, and Aunt May are the cheapest, lowest-impact bodies to cut since this matchup rewards resilient threats over small tokens that die to their removal suite or get swept.
