The Dragon-Kami Reborn

You may look at the cards you exile with The Dragon-Kami Reborn's first two chapter abilities, and you may continue to do so after it has left the battlefield.

If Dragon-Kami's Egg and one or more Dragons you control die at the same time, the ability of Dragon-Kami's Egg will trigger once for each of them. Each time one of those abilities resolves, you'll be able to cast a creature spell from among cards you own in exile with hatchling counters on them.

Each face of a transforming double-faced card has its own set of characteristics: name, types, subtypes, abilities, and so on. While a transforming double-faced permanent is on the battlefield, consider only the characteristics of the face that's currently up. The other set of characteristics is ignored.

Each transforming double-faced card in this set is cast face up. In every zone other than the battlefield, consider only the characteristics of its front face. If it is on the battlefield, consider only the characteristics of the face that's up; the other face's characteristics are ignored.

The mana value of a transforming double-faced card is the mana value of its front face, no matter which face is up.

The back face of a transforming double-faced card usually has a color indicator that defines its color.

A transforming double-faced card enters the battlefield with its front face up by default, unless a spell or ability instructs you to put it onto the battlefield transformed or you cast it transformed, in which case it enters with its back face up.

If you are instructed to put a card that isn't a double-faced card onto the battlefield transformed, it will not enter the battlefield at all. In that case, it stays in the zone it was previously in. For example, if a single-faced card is a copy of Azusa's Many Journeys, the chapter III ability will cause it to be exiled and then remain in exile.
