No sideboard cards are available to bring in for this matchup, so the 75 stays the same. Against Dimir Midrange, Thoughtseize is at its best proactively stripping Counterspell, Force of Negation, or Psychic Frog before they can control the game. Play around Spell Snare when casting two-mana spells like Goblin Bombardment, and note that Ragavan, Nimble Pilferer exiles rather than draws, so it does not trigger Orcish Bowmasters. Fatal Push and Galvanic Discharge answer Psychic Frog and Orcish Bowmasters before they snowball, and pressuring quickly with Ocelot Pride and Voice of Victory denies them time to assemble their counterspell suite.
