Containment Priest is a clean, cheap body that dodges Swords to Plowshares' one-for-one efficiency less than larger threats and adds pressure while being resilient to their bounce/tempo plan; it also stops anything they might try to cheat in, though they have little of that here. Witch Enchanter's destroy-on-entry ability has almost no legal targets against this list, so it's a clear cut. We leave the rest of the proactive core (Thalia, Archon of Emeria, Chalice of the Void) intact since taxing their Force of Will, Daze, Stifle, and cantrips is still the core game plan.
