Echo Mage

If a copy says that it affects “you,” it affects the controller of that copy, not the controller of the original spell. Similarly, if a copy says that it affects an “opponent,” it affects an opponent of that copy’s controller, not an opponent of the original spell’s controller.

If the spell the ability copies has an X whose value was determined as it was cast (like Earthquake does), each copy has the same value of X as the original spell.

Effects that modify a leveler’s power or toughness, such as the effects of Giant Growth or Glorious Anthem, will apply to it no matter when they started to take effect. The same is true for counters that change the creature’s power or toughness (such as +1/+1 counters) and effects that switch its power and toughness.

Echo Mage’s last two activated abilities can target (and copy) any instant or sorcery spell, not just one with targets. It doesn’t matter who controls it.

If you activate Echo Mage’s last ability to copy a spell twice, you may choose new targets for each copy independently. They don’t have to have the same targets as one another. Be sure to specify which of the copies will resolve first.

When either ability resolves, it creates a copy (or two) of a spell. The copies are created on the stack, so they’re not “cast.” Abilities that trigger when a player casts a spell won’t trigger. Each copy will then resolve like a normal spell, after players get a chance to cast spells and activate abilities. Each copy resolves before the original spell does.
