Lands wins through Dark Depths/Thespian's Stage combo for a 20/20 indestructible flier and grinds with Life from the Loam plus Wasteland, so Pithing Needle naming Dark Depths or Thespian's Stage can completely shut off their combo before it resolves. Haywire Mite's sacrifice ability can exile a resolved noncreature artifact like Mox Diamond or an enchantment, providing a bit of extra interaction, and it also gains you 2 life when it dies. Keep the swap small since your Chalice of the Void and Urza's Saga are already strong proactive threats/disruption against their slower, land-based plan, and they have minimal interaction with your Chalice once it resolves on one.
