This site allows you to generate proxy cards for the Magic: The Gathering trading card came. The images are taken from magiccards.info
To create a deck, enter the cards in the large text area below, one card per line. If you're unsure of the card name, the box on the right will attempt to autosuggest card names if you start typing! (requires Javascript)
If you still cannot find it, there is a list of every card (up to Zendikar) here, or use Gatherer.
