Kaladesh Inventions was released in 2016 with 54 foil artifact cards randomly scattered in the Kaladesh block packs. These usually belong to a special set, like Kaladesh Inventions and Amonkhet Invocations. Like I already mentioned, there are some other rarities.

When you get a mythic rare, you’re somewhat more likely to find the one you want from a pack as there aren’t too many mythics in each set. They’re very valuable even if you don’t use them in your decks. That said, you should definitely put them in a sleeve whenever you find one. They have a 1/8 chance to replace rare in any pack, so you won’t get a lot of them. These are the most difficult to come by but are often game-changing.

Rare cards are marked with a golden symbol and are often quite powerful.
