Not to be mistaken with "Supershow".
A supercard (also known as "free-per-view" or "pay-per-view", despite the lack of a real pay-per-view slot) is a federation's (usually monthly) special event, showcasing the ongoing, beginning, or conclusion of major storylines. They usually feature championship matches for most, if not all titles in the federation holding the event. They are not supershows because they are usually intra-federation events.
