Dimir Midrange grinds with Kaito, Enduring Curiosity, and card advantage, so Deep-Cavern Bat is excellent here, stripping their best card (often Requiting Hex, Kaito, or a key removal spell) while applying flying pressure they struggle to block. Dark Confidant races their card advantage plan with more of your own, which matters since this is a long grindy game. Cathar Commando answers Enduring Curiosity (destroying the enchantment half after it dies) and any Clue-generating permanents. Goldmeadow Nomad and Resolute Reinforcements are low-impact tokens that don't pressure their removal-light but counterspell-heavy plan, and Dalkovan Encampment's token generation is replaceable value against a deck with limited sweepers of its own; cutting a land for Dark Confidant here is reasonable since the deck curves low and wants card advantage over flood insurance.
