Monster Summer Sale is a special card set that is related to the Summer 2015 Steam sale. The cards became available on June 11, 2015, the same day as the start of the sale. Prior to that point, it was possible to obtain cards from the Mysterious (2015) set by crafting badges, but these card turned into cards from the Monster Summer Sale set when the sale started.

Cards from this set can be obtained by crafting badges from any game, making purchases on Steam (approx. $10 US per card), or by taking part in the special Monster Summer Game during the sale.
