Dimir Midrange leans on Kaito and Enduring Curiosity as grindy card advantage engines, backed by removal like Bitter Triumph and Shoot the Sheriff that can answer our big Elementals once they land. Impractical Joke stays in: its 3 damage kills most of their creatures, including Dream Beavers and Spyglass Siren (both 1/1), Floodpits Drowner, and Tishana's Tidebinder. It can also hit Kaito as a planeswalker on our turn. Instead we trim Ghost Vacuum, which does little here, and a Sleight of Hand for cheap counterspells that protect our key plays. Spell Pierce taxes their noncreature spells, such as Bitter Triumph, Shoot the Sheriff, and Kaito, though it can't hit Enduring Curiosity because that is a creature spell. Disdainful Stroke stops Kaito or Enduring Curiosity (both MV4) from resolving. Keep the cheap burn in, since their threats are mostly small value creatures rather than aggressive clocks.
