I believe someone is working on a bot that fetches cards but it isn’t up and running yet.
As for iconic/famous cards it does depend on what format you are interested it. Andrew’s comment had some cards that are very well known and from early in the game’s history. There are also the power 9 or P9 that are some of the strongest and most expensive cards in the game. It includes Black Lotus which is arguably the best card ever printed. Later on in Modern and Legacy you have cards that defined the format like Snapcaster Mage, Liliana of the Veil, Dark Confidant (also called Bob), and Tarmogoyf. Sakura Tribe Elder (Steve for short) for a long time was a commander staple. Delver of Secrets is still a card in legacy that has a whole archetype named after it.
