Eldrazi relies on Lotus Petal and Chalice of the Void to accelerate and lock us out, so Null Rod turns off Lotus Petal while Nihil Spellbomb is a cheap artifact that can exile a graveyard and replaces itself for {B} once it goes to our graveyard. Fatal Push comes in to kill their cheaper creatures such as Wastescape Battlemage and It That Heralds the End (mana value 2), and with revolt it also hits mana value 3 and 4 creatures like Glaring Fleshraker, Eldrazi Linebreaker and Thought-Knot Seer. Snuff Out stays in: all of their creatures are nonblack, so key threats like Reality Smasher and Thought-Knot Seer are legal targets, and we can cast it for 4 life when we control a Swamp. Daze comes out because their cheap mana from Lotus Petal and Ancient Tomb makes the {1} easy to pay, and Bilbo comes out too, since its attack trigger risks walking into removal. Prioritize Wasteland and Thoughtseize to strip their hand and mana before Chalice of the Void locks us out.
