This is effectively a mirror match, so the primary axis of advantage is who resolves an unanswered Armadillo Cloak on a Guardian of the Guildpact first — Deglamer comes in as instant-speed enchantment removal to break up that combination before it runs away with the game. Flaring Pain is the single most impactful sideboard card here: played in response to Prismatic Strands it turns off the fog entirely, and it also negates Armadillo Cloak's lifelink on the turn it matters most, keeping life totals close when you press through for damage. Faerie Macabre disrupts the Midnight Tilling recursion engine, denying the opponent the land and creature cycling that powers their late-game inevitability. Thraben Charm is trimmed because its artifact-destruction mode is nearly dead against this list, and Gatecreeper Vine is shaved since both players flood the board with gates anyway and additional ramp is marginal once the game is in a grindy midgame. Play patient, hold up interaction, and aim to resolve your Armadillo Cloak only when you can protect it.
