Right now, the text of a card is shrunk until it can fit inside the card, both in collection and in combat, up to the point of being unreadable.

Which mean that if you don't know the text of the card, like how it is excepted to happen in a regular match, you will need to search for the card in your opponent's collection, and try to edit it to see the text, and if they didn't create it you may never know what's written on it (except any abilities appearing in the log) because the card's creator isn't indicated during a match.
