3.1Building a deck
- 3.1.1
A deck holds 30 to 80 cards.
- 3.1.2
A deck holds at most 3 copies of any one card.
- 3.1.3
- 3.1.4
There is no rule about attributes: a deck may hold Light cards, Dark cards or both.

In online play, a deck you built yourself may only hold cards you own; the ready-made starter and theme decks can be played by everyone. Duels against the computer opponent and the deck test follow the same deck rules.
