Amulet Titan runs only four basic Forests, relying on bounce lands like Simic Growth Chamber and Gruul Turf plus Urza's Saga to enable its ramp; Blood Moon (Enchantment) turning those into Mountains strips their bounce-land text (so they no longer return a land to hand for free value) and shuts off Urza's Saga's chapter abilities before it can find an artifact. The extra Teferi, Time Raveler forces their instant-speed interaction (Dismember, Force of Vigor) down to sorcery speed on their own turn, buying time for your own threats to stick. Goblin Bombardment and a Ragavan, Nimble Pilferer come out, as Bombardment offers little value against large threats and Ragavan is easily blocked by Arboreal Grazer. Keep Consign to Memory, Solitude, and Galvanic Discharge in to counter key triggered abilities or answer a resolved Primeval Titan or Cultivator Colossus before it takes over the game.
