Weiss Schwarz Deck Construction Rules

Summary of the official rules used to validate your decks on TCGNiche.

Deck size

Your deck should contain exactly 50 cards with a maximum of 8 Climax cards.

Deck pile

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.

Card copy limit

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.

Side (Weiss / Schwarz)

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.

Neo-standard format

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.

Neo-standard restriction list

Some cards are banned or limited to fewer than 4 copies by the publisher, independently of the general rule above.
