Forum:Errata'd cards

Hi, what means a card is errata'd? For example, a friend has a Ocean Dragon Lord - Neo-Daedalus and it doesn't mention it needs a Levia-Dragon - Daedalus to be special summoned, is that right? The errata'd card is a correction? They work similar or each one works as its text says? Hurin dueler 16:30, 25 January 2009 (UTC)
