Dimir Self-Bounce leans on Stormchaser's Talent's recursion and various bounce/tempo effects rather than heavy land destruction targets, so Field of Ruin and two Demolition Field come out. Rest in Peace exiles their graveyard, shutting down Stormchaser's Talent's level 2 ability to return instants/sorceries and denying any incidental graveyard value. Authority of the Consuls provides incremental life gain and slows their tempo creatures like Fear of Isolation. Keep your full removal suite active against their few real threats and prioritize disrupting their bounce loops before they can reset Narset, Parter of Veils or Momentum Breaker.
