Selesnya Enchantress can't interact with your board at all early, so Xantid Swarm lets you attack for free while also shutting off their ability to draw into or protect their engine on your attack step. Tranquil Domain is a powerful one-sided answer here, destroying all non-Aura enchantments and wiping out Enchantress's Presence, Sterling Grove, Solitary Confinement, and a resolved Opalescence in a single shot since you run no enchantments of your own to lose. Crystal Vein and Sky Diamond come out since you don't need extra colorless acceleration in a matchup this slow — you have plenty of time to assemble Tinker into Phyrexian Devourer without rushing your mana. Keep Tsabo's Web in the maindeck as is, since it still punishes their Serra's Sanctum and any tapped utility lands they run.
