The Legend of Yangchen

Each face of a nonmodal double-faced card has its own set of characteristics: name, types, subtypes, abilities, and so on. While a nonmodal 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.

Permanents chosen by players using The Legend of Yangchen's first ability will be exiled simultaneously once all players have chosen permanents.

Each nonmodal 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.

You must choose a target opponent for The Legend of Yangchen's second chapter ability when it is put on the stack. You will not choose whether or not that opponent will draw cards until the ability resolves.

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 The Legend of Yangchen, the chapter III ability will cause it to be exiled and then remain in exile.

A nonmodal double-faced card enters 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.

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