This is a matchup against an enchantment-based engine, so Aura of Silence taxes their enchantment spells and can later be sacrificed to destroy a key enchantment like Sterling Grove or Solitary Confinement (note that Sterling Grove gives their other enchantments shroud, so hit the Grove itself first). Ray of Revelation adds more cheap enchantment removal with flashback redundancy, while Tormod's Crypt can exile their graveyard to blank Replenish and is free to cast. Armageddon remains a key out, since it destroys their lands, including Serra's Sanctum, which Aura of Silence can't touch. Small creatures like Werebear and one Wild Mongrel come out since this matchup is about disruption and land destruction, not board presence.
