This is a White based prison deck that is trying to cast Enduring Ideal as soon as possible. We can ramp into our namesake card with both Lotus Bloom and Nykthos, Shrine to Nyx. Once Enduring Ideal is cast we lock our opponent out of the game with enchantments like Dovescape, Overwhelming Splendor, and Sphere of Safety. Eventually we win the game on the back of Form of the Dragon dealing five damage a turn.
