UB Tempo runs a similar cantrip-and-disruption shell to your own deck, using Thoughtseize and Stormchaser's Talent alongside Force of Will and Flow State to protect its threats, so cheap, free interaction is at a premium. Consign to Memory strips a Force of Will or Thoughtseize from their hand before your combo turn, effectively winning the disruption exchange for zero mana. Bitter Triumph is efficient removal for a resolved Stormchaser's Talent-boosted creature or other key permanent. Mishra's Bauble and Street Wraith are marginal cantrips you can cut for real interaction in this disruption-heavy mirror-adjacent matchup.
