This mirror-like Mono-Green matchup comes down to who sticks the bigger threats first and who can answer Craterhoof Behemoth, so Arasta of the Endless Web gives you a sturdy 3/5 reach body that can block Badgermole Cub or Vastlands Scavenger while still contributing tokens. The Stone Brain is a strong proactive answer, letting you exile all copies of Craterhoof Behemoth from their hand, graveyard, and library before it ends the game. Polukranos Reborn is replaceable since it doesn't meaningfully out-size their threats, and one Ulvenwald Oddity comes out to balance the swap without touching lands. Keep an eye on their Boseiju, Who Endures, which can destroy your Nykthos or Leyline of the Guildpact if left unchecked.
