Emerald Dragon // Dissonant Wave

If an effect instructs you to choose a card name, you may choose the alternative Adventure name. Consider only the alternative characteristics to determine whether that is an appropriate name to choose.

Activated and triggered abilities from noncreature sources include abilities of noncreature cards that can be activated or triggered from other zones, such as cycling abilities.

Abilities that create replacement effects, such as a permanent entering the battlefield tapped or with counters on it, can't be targeted. Abilities that apply “as [this creature] enters the battlefield” are also replacement effects and can't be targeted.

You must still follow any relevant timing rules for the permanent spell you cast from exile. Normally, you’ll be able to cast it only during your main phase while the stack is empty.

An adventurer card is a permanent card in every zone except the stack, as well as while on the stack if not cast as an Adventure. Ignore its alternative characteristics in those cases. For example, while it’s in your graveyard, Altar of Bhaal is an artifact card whose mana value is 2.

Mana abilities can't be targeted. An activated mana ability is one that could produce mana as it resolves, doesn't require a target, and isn't a loyalty ability. A triggered mana ability is one that could produce mana as it resolves, triggers on the resolution of an activated mana ability or on mana being added, and doesn't require a target.
