Azorius Replenish's entire game plan lives in enchantments — Opalescence, Parallax Wave, Decree of Silence, Attunement — so Reverent Silence blowing up all enchantments as a Sorcery can undo a resolved Replenish in one card. Naturalize is a cheap, efficient way to strip Opalescence or a Parallax Wave before it locks down your board. Frantic Search and Daze are less impactful since the games is more about racing their Ancient Tomb-fueled draws than winning tempo exchanges, so they make room. Try to apply pressure with Wild Mongrel and madness creatures before Replenish resolves, since afterward Parallax Wave can exile your team.

Mono-Blue Stiflenought has no red spells or permanents, so Blue Elemental Blast and Hydroblast are dead, while Naturalize can target their Phyrexian Dreadnoughts as well as Powder Keg. This matchup is decided by the Daze and Mana Leak war over their Phyrexian Dreadnought and Stifle-based combo, so the maindeck's countermagic stays in unchanged (though Wasteland cannot target their basic lands for Gush/Foil alternate costs). Prioritize using Survival of the Fittest to find Gilded Drake as a one-sided answer to a resolved Phyrexian Dreadnought, since it exchanges itself for their 12/12. Careful Study and Frantic Search should be sequenced to hold up Daze mana whenever possible.

Gruul Goblins fields an army of 1- and 2-toughness bodies (Goblin Lackey, Mogg Fanatic, Matron, Ringleader, King, and Siege-Gang's tokens), making Pyroclasm a near-blowout that clears their board for 2 mana. Blue Elemental Blast answers a key red permanent like Goblin Warchief while countering key red spells. Daze is weak here since it costs you tempo against a deck that doesn't care about card advantage, and Mana Leak is too easily played around once they have Rishadan Port mana up, so both come out. Keep Wild Mongrel and Basking Rootwalla in to race and use Survival of the Fittest to find Gilded Drake against their bigger threats like Siege-Gang Commander.
