I, II - You gain 2 life. Look at the top three cards of your library. Exile one of them face down with a hatching counter on it, then put the rest on the bottom of your library in any order. // III - Exile this Saga, then return it to the battlefield transformed under your control. //// Dragon-Kami's Egg // Enchantment Creature - Egg // Whenever Dragon-Kami's Egg or a Dragon you control dies, you may cast a creature spell from among cards you own in exile with hatching counters on them without paying its mana cost.
