Dimir Tempo wants to disrupt our hand and resolve a resilient threat like Murktide Regent or Tamiyo, so Abrupt Decay is premium since it can't be countered by Daze or Force of Will and kills Tamiyo, Inquisitive Student or an early Nethergoyf cleanly. Disruptor Flute is excellent here, naming Murktide Regent or Daze to blunt their key cards or tax their disruption. Barrowgoyf is awkward against a deck that will mill/escape and interact with graveyards less aggressively but still fine; we trim a couple copies since they compete with the new answers and we don't need the full count against a non-artifact-heavy opponent. Keep Wasteland and the full mana engine since this is a resource war where hitting land drops matters.
