Blood Moon is devastating against Amulet Titan since it turns their bounce lands (Simic Growth Chamber, Gruul Turf), Urza's Saga, and utility lands into Mountains, stranding most of their mana engine and Primeval Titan payoffs. Consign to Memory counters colorless spells and triggered abilities for free when replicated, hitting things like Urza's Saga's construct ability is not legal since that's an activated ability it can't target, but it does stop colorless spells like Crumbling Vestige's enters-the-battlefield trigger — note triggered abilities are covered by its text, making it useful against their ETB-heavy plan. Spell Snare is weak since few of their key cards sit at mana value 2, and Lightning Bolt has limited good removal targets against noncreature-heavy ramp, so both get trimmed. Keep Counterspell and Force of Negation ready for Scapeshift or Primeval Titan, and deploy Blood Moon as early as possible to lock their mana down.
