Rest in Peace is devastating here, exiling their graveyard on entry and shutting off Goryo's Vengeance's ability to reanimate Atraxa or Griselbrand entirely, while also stopping any further graveyard value. Consign to Memory counters colorless spells and triggered abilities, which can disrupt Quantum Riddler's draw trigger timing indirectly by countering it as a triggered ability. Galvanic Discharge and Thraben Charm are too slow and low-impact against a combo deck trying to cheat in a 7/7 or 4/4 reanimation target, so proactive graveyard hate matters more than small removal. Keep Solitude since exiling their Psychic Frog or a reanimated threat is still very relevant.
