Each player will receive 6 booster packs, 1 prerelease pack, and 1 P-071 Marco
– 6 Packs (each participant should use the same number of packs.)
– You may bring your own leader (including those from previous sets) to use in the event.
– Please bring 10x DON!! Cards to participate in the event.
Deck Construction Rules
After opening 6 packs, players build a 40-card deck, and a 10 DON!! card deck. There are
no banned or restricted cards, and players can include as many copies of cards with the same
card number as they like. (There is no 4-card limit and 5 or more copies of a card with the
same card number can be included in decks.) Any cards left over from deck construction are
treated as sideboard cards.
Special Game Rules
– In sealed format games, players can ignore deck colour requirements based on their leader.
