Dimir Tempo backs Tamiyo, Inquisitive Student and Murktide Regent with Thoughtseize, Force of Will, and Daze, so cheap unconditional removal that dodges card disadvantage is key. Static Prison and Portable Hole exile their early threats before Tamiyo flips or Murktide gets big off delve, denying the tempo plan entirely. Warping Wail can kill an Orcish Bowmasters or Brazen Borrower for one mana, or counter a cheap Daze/Ponder when they're tapped low. Cut the top-heavy Tezzeret and Fleshraker copies, which are too slow against a deck designed to Thoughtseize and Force your best cards away.
