Is there a way to know exactly when a card has received an erratum?
There are some websites like yugipedia or yugioh wiki that collect card errata showing the first edition reprinted after a certain error, but the release date of those reprints isn't necessarily the date since the erratum is valid.
Cards like Firewall Dragon were reprinted some time after the last error and others like Darkness Approaches have never been reprinted since the last erratum.
