BR is another graveyard-centric aggro-midrange deck relying on Nethergoyf, Stitcher's Supplier, and Thoughtseize. Dauthi Voidwalker exiles their self-mill fuel before it hits their graveyard and provides an evasive clock. Spell Snare is a narrow but cheap answer: the only mana value 2 spell in their main deck is Fear of Missing Out, so hold it for that and don't expect it to stop Thoughtseize (mana value 1) or Flare of Malice (mana value 4). Thought Scour is redundant self-mill that doesn't help us race, and Persist is too slow against their efficient removal and pressure. Keep Fatal Push and Thoughtseize to proactively disrupt their hand and kill Nethergoyf early. Be aware of their sideboard cards: Meltdown only destroys artifacts, and we run none in our main deck, so it's mostly dead against us. Obsidian Charmaw can destroy one of our many nonbasic lands while applying a flying clock.
