Terrageddon plans to blow up our mana base with Armageddon after building a board advantage, so Krosan Reclamation helps us recur lands or key enchantments from the graveyard back into our library to redraw after a reset. Ray of Revelation destroys a problematic enchantment like Sylvan Library, and its flashback lets us do it twice across the game for a single green mana the second time. We trim Opalescence and Replenish since neither helps us rebuild quickly after an Armageddon, and our Exploration and Wild Growth already provide enough mana resilience without needing extra enchantment synergy pieces that do nothing to answer their land destruction plan.
