Summary of the official rules used to validate your decks on TCGNiche.
Your deck should contain exactly 50 cards with a maximum of 8 Climax cards.
Place your deck here face-down. You are not allowed to change the order of these cards in any way unless stated by an effect. Your deck refreshes when it runs out of cards.
A deck may contain at most 4 copies of the same card (same card number), unless that card appears on the restriction list below, in which case the limit shown for that card applies instead.
In Side Constructed format, a deck can only mix cards from a single side (Weiss "W" or Schwarz "S") — see the side field on deckbuilding.deck.
In Neo-standard format, a deck may only contain cards belonging to the Neo-standard codes allowed for that deck (typically those of a single title/series, see catalog.neo_standard_code and deckbuilding.deck_neo_standard_code). A deck can combine several Neo-standard codes when the official rule allows it for that series.
Some cards are banned or limited to fewer than 4 copies by the publisher, independently of the general rule above.
