This is a grindy artifact-lands race where Ancient Stirrings, Urza's Saga, and Malevolent Rumble fuel their Eldrazi threats, so extra Tormod's Crypt slows their Emrakul, the Promised End (whose cost reduction relies on graveyard card types). Veil of Summer is still useful as protection, making our spells uncounterable for the turn and giving us and our permanents hexproof from blue and black, which is relevant if their sideboard brings in blue or black interaction. Nature's Claim answers Blade of the Bloodchief or a resolved artifact threat cheaply. We already have Haywire Mite in the 75 as an extra artifact/enchantment answer, so we trim redundant utility (Boomerang Basics, Sewer-veillance Cam, Grinding Station, Haywire Mite, Six) that does little against their board-based plan.
