Terrageddon's Armageddon plan is devastating against our land-dependent deck; Abeyance can stop Armageddon if we cast it during their turn (for example in their upkeep) targeting them, since it only lasts until end of turn and Armageddon is a sorcery. It also cantrips, so holding it up costs us little. Tsabo's Web keeps Rishadan Port, Treetop Village, and Mishra's Factory from untapping once they use their abilities, slowing their land disruption and manland pressure, and it replaces itself with a card. Mana Leak and a copy of Intuition are cut since this matchup is about resolving our combo quickly before Armageddon strands us, not card selection. Replenish into Opalescence plus Parallax Wave is a fast way to build a board, and since Armageddon only destroys lands, our enchantments stay on the battlefield after it resolves.
