“Selesnya Enchantress is a combo-control deck that leverages Argothian Enchantress and Enchantress's Presence as card draw engines, chaining enchantment plays to generate overwhelming card advantage. Serra's Sanctum provides explosive mana acceleration by tapping for one mana per enchantment in play, while Solitary Confinement serves as the primary lock piece, becoming effectively indestructible when the enchantress draw engine is running and supplying a fresh enchantment each turn to pay its upkeep. Sterling Grove protects the engine pieces from disruption while also tutoring for any enchantment needed to complete a combo or shore up a specific matchup.”

Buy sideboard on ManapoolThis matchup is a race to assemble engines, and Aura of Silence is excellent, taxing their enchantment spells like Opalescence, Attunement, Parallax Wave, and Decree of Silence while giving us a way to blow up a resolved Opalescence or Decree. Swords to Plowshares is weak since they have almost no creatures to exile, so both copies come out. Parallax Wave does little against a deck with few creatures to exile, so we trim it for more disruption. Tormod's Crypt strips their graveyard before Replenish can reanimate it, and Karmic Justice punishes their Seal of Cleansing or enchantment removal aimed at our permanents. Keep Sterling Grove up to protect our own enchantments and tutor for Aura of Silence or Seal of Cleansing as needed.
Xantid Swarm shuts off their entire turn of countermagic when it attacks, letting our enchantment plays resolve uncontested against their wall of fifteen counterspells and ability counters. Aura of Silence taxes Phyrexian Dreadnought by {2} directly as an artifact spell and can sacrifice to destroy a resolved Dreadnought outright. Swords to Plowshares stays in as our cleanest one-mana answer to the Dreadnought, and Solitary Confinement remains a core engine piece that also stops all damage from a Stifled 12/12. Parallax Wave and the extra Abeyance are the weakest non-core cards against a deck with only one creature type to interact with, so they make room.
This Goblin aggro deck wants to flood the board and attack fast, so Abeyance is excellent, stopping their instant-speed tricks and non-mana activated abilities like Goblin Sharpshooter or Mogg Fanatic for a full turn while drawing a card. Aura of Silence doesn't interact with their mostly creature-based plan directly but its sacrifice mode can destroy a problematic artifact or enchantment like Powder Keg if they bring one in, and it's a reasonable rate enchantment to feed our draw engine. Opalescence is risky since it turns our enchantments into creatures that their burn and combat can trade with, so we trim it. Parallax Wave only buys temporary tempo against a deck that rebuilds its board quickly with Goblin Ringleader and Siege-Gang Commander, so it comes out along with the extra Replenish for more proactive disruption.
