Domain Zoo is a low-curve aggressive deck (Territorial Kavu, Ragavan, Scion of Draco) that wants to flood the board quickly, so Wrath of the Skies sweeps their cheap threats even at a modest energy payment while your bigger creatures survive. White Orchid Phantom is particularly strong since their domain and Scion of Draco payoffs depend on a wide variety of basic land types across many nonbasic duals and fetches — destroying one of those lands can meaningfully set back their color fixing while adding an evasive clock. Thoughtseize is less impactful against such a proactive low-curve deck, and Faithful Mending is too slow against their speed, so both get trimmed. Solitude and Prismatic Ending remain key for answering an early Territorial Kavu or Ragavan before it takes over.
