Wraith of Echoes

Wraith of Echoes

Q: Does Wraith of Echoes trigger on its own death?

No. Units don't "see" themselves die unless they have an ability such as Deathknell that explicitly allows them to. For clarity, we are issuing an errata that adds the word "another" to Wraith of Echoes.

Wraith of Echoes

The first time another friendly unit dies each turn, draw 1.

Q: What about other units that die at the same time as Wraith of Echoes, such as to a mass damage spell like Unchecked Power?

No. Units that die also don't "see" anything else that dies at the same time they do.

Q: What happens if the first time a unit dies in a turn is actually two or more units dying simultaneously? Does it trigger twice?

Just once. If an ability triggers "the first time" something happens and that trigger condition is met multiple times simultaneously, you'll pick one to count as the first.

383.1.b. If an ability triggers "the [Nth] time" something happens and that trigger condition is met multiple times simultaneously, the ability's controller picks one of those instances to serve as the trigger condition. The ability triggers only once, due to the chosen condition. Example: Wraith of Echoes reads "The first time another friendly unit dies each turn, draw 1." That ability hasn't triggered yet this turn. Two other friendly units die simultaneously (say, due to combat damage). The Wraith's controller chooses one of those deaths to trigger Wraith's ability.
