Replicate {U} (When you cast this spell, copy it for each time you paid its replicate cost. You may choose new targets for the copies.)
Return target nonland permanent and each other nonland permanent with the same mana value as that permanent to their owners' hands.
A copy of a spell can be countered like any other spell, but it must be countered individually. Countering a spell with replicate won't affect the copies.
If a permanent has {X} in its mana cost, X is 0 when determining its mana value.
If the target nonland permanent is an illegal target as Mists of Lórien tries to resolve, it won't resolve and none of its effects will happen. No permanents will be returned to their owners' hands.
