Collection

Collection is a game term referenced on the Come On Victory card.

It also refers to the cards that one owns outside of their deck, such as in a card binder.

Details

DMX-12 Black Box Pack had many unique features among its cards. On Come On Victory, it marked the first and only time that a players total card collection was referenced, as well as an ability that allowed you to open a booster pack from Episode 2 or Episode 3 and use that card during the current game.

Come On Victory
Water / Spell / 3
Shield trigger (When this spell is put into your hand from your shield zone, you may cast it immediately for no cost.) Open a (Episode 2) or (Episode 3) booster pack, choose a card from among them and put it into your hand. Put the rest of cards into your collection.

The next black box pack, DMX-22 Super Black Box Pack introduced 2 new cards that add cards to a players collection;

• Come On Legend
• Pack E, the Super Electromagnetic

In the second definition

A collection also refers to the cards outside a player's deck, usually for viewing or show purposes. A person who rarely duels but collects real life cards is known as a Card collector.

While High collect-ability cards are usually assumed as old cards by unsuspecting players, the truth is old cards usually deflate in value as most of these cards are useless in competitive play. In reality, high rarity promotional cards such as WINNER Cards, Winner Awards and Secret versions of Victory Rares are more likely to have high collection value and thus fetch higher prices than old cards due to their historical value, low availability or high usefulness in the Metagame.
