Echoes are a new edition of Digital Collectible cards that are created through Replication. Replication is an imperfect process, there’s a chance an anomaly will also be created alongside the intended echo. Anomalies may be visual marks or slightly altered appearances of the original artwork. Anomalies may also materialize as additional echoes, in-game progression or exclusive cosmetics.
