Dimir Excruciator wants to strip our hand with Duress and Deceit, then close the game with Doomsday Excruciator or removal like Bitter Triumph and Requiting Hex, so Voice of Victory is excellent to protect our development from instant-speed removal on our turn. Omni-Changeling and Terror of the Peaks give us resilient, hard-to-answer threats that punish them for tapping out. Lost in the Maze is weak since they don't flood the board with creatures early, and Prismari Charm's small modes underperform against their bigger threats like Superior Spider-Man and Doomsday Excruciator, so both are trimmed. Play around Duress and Deceit by sequencing our most important spells carefully.
