The Dragon-Kami Reborn // Dragon-Kami's Egg

(As this Saga enters and after your draw step, add a lore counter.) 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.

===

Whenever this creature 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.
