Mono-Red Sligh has essentially zero interaction with your combo plan — no counterspells, no graveyard hate — so this matchup is a pure race where you need to resolve Hermit Druid and go off before their burn suite closes out the game. A single Duress can proactively strip away a potential Overload or other sideboard surprise, though it's a minor value-add rather than a necessity. Keep the deck as close to its default configuration as possible since speed and consistency matter far more than any specific silver bullet here. Mulligan aggressively for hands that can activate Hermit Druid quickly.
