Thoughtseize proactively strips Ragavan, Nimble Pilferer, Leyline Binding, or a key burn spell before this fast, low-curve aggro deck can deploy it. Buried Alive is too slow against Domain Zoo's aggressive clock and doesn't address their removal suite, so it comes out. Witherbloom Charm's destroy mode answers Wild Nacatl or Territorial Kavu cheaply, and the life gain mode can offset their burn (Lightning Bolt, Tribal Flames). Timeline Culler's body is unimpressive against their efficient removal, so we trade a couple copies for disruption.
