“Azorius Replenish is a combo-control deck that uses Attunement and Frantic Search to rapidly cycle enchantments into the graveyard, then reanimates them all at once with Replenish. The primary win condition is resolving Opalescence alongside Parallax Wave or Decree of Silence to lock the opponent out of the game while attacking with animated enchantments. The deck uses counterspells and Swords to Plowshares to survive long enough to assemble the combo, with Ancient Tomb providing the fast mana needed to deploy threats ahead of schedule.”

Buy sideboard on ManapoolThis matchup is a race to resolve our engine before Phyrexian Dreadnought closes the game in two swings; Mana Leak is often too slow against Daze/free-counterspell backup so we trim to one and bring in additional artifact removal. Seal of Cleansing can outright destroy a resolved Dreadnought. Prioritize Swords to Plowshares on a resolved Dreadnought since it exiles regardless of color. Keep the full counter suite otherwise since this is a counter war.
Mono-Red wants to race with burn and efficient creatures before we assemble our lock, so Mana Leak is too slow against a curve full of one-and-two-drops backed by Fireblast reach. Abeyance buys a full turn to deploy Opalescence/Parallax Wave safely and cantrips to keep gas flowing. Seal of Cleansing answers Cursed Scroll and Seal of Fire before they chip in extra damage. Keep Swords to Plowshares and Parallax Wave as our main lines of defense against their creatures.
This is a mirror-style enchantment battle where Seal of Cleansing is premium, so we bring in the second set to blow up Sterling Grove or Solitary Confinement on demand. Meddling Mage comes in naming Enchantress's Presence, Sterling Grove, or Solitary Confinement to strangle their engine before it starts. Mana Leak is weak since they can easily pay the {3} off mana like Serra's Sanctum, and Swords to Plowshares has almost no targets against a deck built around noncreature permanents. Intuition is cut back since our own engine pieces are less urgently needed against a deck that isn't racing us or attacking our life total. Keep the full core engine of Replenish, Attunement, Opalescence, Parallax Wave, and Decree of Silence intact, since Decree of Silence is especially strong at shutting off their enchantment-heavy spell sequence.
