Important Notice on Tournament Participation

Key Points for Deck Registration

• Deck registrations on Bushi Navi are required for this event. Please complete any deck registrations before the start of round 1.
• Deck checks will be conducted to ensure that the registered deck and the actual deck used are the same.

What Does "Deck Check" Mean?

Tournament officials and staff at the stores where tournaments are being held will verify that the contents of the physical deck match the deck registered on Bushi Navi.
If any discrepancies are found between the deck and the registered contents, the player will be disqualified and will also forfeit any tournament prizes.

What Should I Look Out For?

For the Oshi holomem card and main deck, please ensure that all card numbers match the contents of your registered deck.
For the cheer deck, please ensure that all card names match the contents of your registered deck.

*Card rarities do not have to match exactly.

Regarding Extra Turns

Extra turns refer to the additional turns required to determine a winner after time is up for that game.
The following steps will be used for turn progression and determining the winner.

1. At the point where the end of a game is announced, all play is suspended, even if it is in the middle of an ability/effect resolution, and a judge is called.
2. The number of extra turns awarded when time is called will differ depending on the player who is playing the current turn, based on whether they were the player who is going first or going second for the game.
   

   [If the player going first for the game is playing the current turn when time is called]
   The player going first in the game will continue to play out their current turn, and the player going second will play an additional turn after that.
   [If the player going second for the game is playing the current turn when time is called]
   The player going second in the game will continue to play out their current turn, then the player going first will play an additional turn, and thereafter the player going second will get an additional turn.

3. If a winner cannot be determined even after the extra turns are played out, the player with the most life remaining will be declared the winner. If both players' remaining life is the same, the next turn will proceed, and the game will continue until the end phase of that turn or until a winner can be determined. Repeat step 3 with additional turns proceeding, until a winner is decided.
   In the event that both players lose at the same time during the extra turns, the non-turn player shall be declared the winner.

Points to Take Note After the Tournament

Please remain in your seats or the tournament area after the final match, and await instructions from the hosting store or tournament officials.

*The champion prize and top cut prizes will be forfeited if you are absent without permission when prizes are awarded.
*To prevent cheating, there may be cases where the tournament officials retain the decks used even after the final matches for investigation purposes. Please follow the instructions from staff/officials on the actual day of the tournament.
