Temur Indomitable Creativity wants to resolve Indomitable Creativity or Fable of the Mirror-Breaker uncontested, so Thoughtseize and Duress proactively strip their key combo/value pieces before they can go off. Soul-Guide Lantern is a cheap artifact that can exile a card from a graveyard when it enters, and it can later be sacrificed to draw a card, which gives us an extra artifact to sacrifice. Voldaren Epicure's small body and ping are not very relevant against their bigger late-game threats like Worldspine Wurm or Raph & Mikey, so those come out along with some Torch the Tower given their high-toughness finishers survive the 2-3 damage.
