Amulet Titan wants to ramp into Primeval Titan or assemble Urza's Saga value, so Wear // Tear is useful to destroy Urza's Saga or an Amulet of Vigor before it generates excess value. Vexing Bauble raises the floor on their cheap interaction and free spells. Consign to Memory has limited targets since this deck casts few colorless spells, and Lightning Bolt is a weak removal spell against their ramp-oriented, low-creature-count plan, so both are trimmed slightly. Focus your own clock on racing them before Primeval Titan or Scapeshift assembles a game-ending board.
