While deckbuilding refers to the process of making your deck inside the gameplay to play with through a run (like in Heretic’s Fork), some Roguelike deckbuilders like Star Survivor have a particular style of metaprogression that includes unlocking cards to be put into a “deck” for runs (deck construction.) Deck here is applied pretty liberally, very few of these games play like card games. In the survivors-like subgenre, chances are your “cards” chosen will be used for automated attacks or equipped in some way.
