Spark is the crafting currency in Plants vs. Zombies Heroes, introduced at the 1.4.14 update. Sparks can be obtained by recycling premium cards that the player owns, and is used to craft new ones the player chooses, and getting them from Hero Quests.
To craft a card, the player only needs to access a plant/zombie's statistics page in the Collection, and once selected, two choices will appear, craft and recycle. Any of these two options can be reversed until the player leaves the Collection.
The player has to connect to the internet in order to craft cards. If not, after exiting, they won't get any cards and will have their sparks back.
