The newest Tryout Duel event, Time Travel 2004, will run until March 4th (time zones applying). By winning 3 Duels, you can obtain 1 pack of the most recent reprint pack, The Forbidden Liberated.

The special rules for this event limit the card pool to November 25th, 2004, which is the release date for the OCG version of Flaming Eternity. This is chronologically slightly earlier than the popular “Goat Format” (April 2005). The player going first will also draw a card. The Extra Deck is still limited to 15 cards, and the Main Deck is limited to a maximum of 60 cards.
