Blood Moon is largely dead here since Eldrazi's core lands (Eldrazi Temple, Cavern of Souls, Eye of Ugin, Ancient Tomb) are nonbasic but they also run basic Mountain and their colorless-heavy manabase isn't crippled the way a multicolor deck's would be, so we trim to a thin 1 copy via cutting 2, keeping it mainly as a mirror-breaker against Chalice of the Void lines. Disruptor Flute can name Thought-Knot Seer or Reality Smasher to tax their key threats by {3}, slowing their clock significantly. Pithing Needle can shut down Eye of Ugin's tutor ability or stop Lotus Petal-adjacent value engines. Lavaspur Boots is weak since Eldrazi creatures are already large and the +1/+0 and ward 1 don't meaningfully change combat math against Reality Smasher or Thought-Knot Seer.
