Maverick leans on Wasteland and Thoughtseize to disrupt our mana and hand while applying pressure with Hogaak, Arisen Necropolis and Wight of the Reliquary, so Disruptor Flute naming Wasteland or Thoughtseize taxes their disruption suite significantly. Transmute Artifact is a liability against a deck with proactive disruption and no reason to interact with the stack, so trimming it for a cheaper, more resilient hatebear-style answer is better here. Our Urza's lands (Urza's Saga, Urza's Tower, Urza's Workshop) give us resilience against individual Wasteland activations since we have redundant mana sources. Keep Kozilek's Command as flexible removal for Wight of the Reliquary or Orcish Bowmasters.
