This matchup is about denying the Replenish combo rather than racing. Naturalize and Tranquil Domain (destroying all non-Aura enchantments) are live answers to Opalescence, Parallax Wave, and Decree of Silence, while Tormod's Crypt strips the graveyard before Replenish can return everything at once. Extra Duress backs up the existing copies to strip Replenish or a counterspell before it resolves. Ravenous Rats, Graveborn Muse, and Chainer's Edict come out since the opponent fields almost no creatures worth attacking or edicting. Keep Cabal Therapy and Pernicious Deed in as they can strip or blow up the enchantment lock pieces as well.

Phyrexian Dreadnought is the only real threat. It's sacrificed on entering unless they sacrifice 12 power of creatures, so it mostly sticks only when they Stifle the trigger. Once it does stick, it dies to Smother (mana value 1), Chainer's Edict, Pernicious Deed, or Naturalize, since it is an artifact creature. Their deck runs essentially no other creatures, so the edicts stay in: they have nothing else to sacrifice. Naturalize stays in too, because it hits the Dreadnought and Powder Keg. The extra Smother gives another clean answer. Vendetta stays in the sideboard because killing a 12-toughness Dreadnought with it costs 12 life. Tormod's Crypt is low-impact here but can stop a Flash of Insight flashback if timed well, and it's a cheap play alongside Duress for stripping a counterspell before deploying a threat. Keep Duress and Cabal Therapy in as maindeck disruption against their counterspell-heavy plan. Dust Bowl comes out since they have no nonbasic lands to hit, and Recurring Nightmare and Haunting Echoes are too slow and situational against a deck of counterspells and cantrips.

Ravenous Baloth's 4/4 body is excellent at blocking their aggressive goblin horde and can gain back life lost to burn spells like Lightning Bolt and Incinerate. Tormod's Crypt is a low-cost way to exile their graveyard, denying any graveyard-based recursion and limiting their flashback plays. Ravenous Rats are too small to matter against a deck built to go wide and overwhelm 1/1 blockers, and Naturalize has almost no targets since Goblins run very few artifacts or enchantments. Keep Pernicious Deed and Wall of Blossoms in as your core answers to their wide boards.
