This is where we come in. During a tournament, you are allowed to ask a judge for Oracle text on any card if you can provide a unique identifier (usually name, but if you can’t remember that, other attributes that identify the card clearly are also okay).
Cards may have received errata for a variety of reasons: due to printing errors, to add/change a creature type, or to update text on an old card that can’t actually function under current rules as it’s written. It could just be that a card is in a language you can’t read or has been altered in a way that you can’t read all the text.
So any time you want to see the Oracle text for a card, for any reason (it doesn’t have to be a card that is currently visible in the game), just call a judge and ask. You can even ask away from the table, to avoid giving your opponent information.
