The Battle Spirits Special Investigation Team has been researching the game balance of Battle Spirits to the best of their abilities in order for players to enjoy Battle Spirits.
This time, we have confirmed that using [BS77-CX01 The Burning Blade Flag Bearer, Saber] allows the construction of a faster and better loop deck. Hence, the following cards will be added in to the banned and restricted list from November 21, 2026 2026 (Sat.) onwards as an emergency measure.

「BS46-RV009 Ardor Flame」, 「BS46-RV010 Totentanz」, 「BS46-RV011 Dream Hand」, 「BS46-RV012 Royal Potion」 has an effect to return cores from your trash to your reserve at the beginning of your main step.
Using this effect together with「The Burning Blade Flag Bearer, Saber」which adds an additional main step, you can expand all your cores during your first main step, with powerful draw power to get what you need for the loop to prepare for your next step of the loop during your second main step. As such, you can complete your loop and achieve victory with better speed and stability than before. As such, these 4 cards will not be restricted to <1> but instead, designated as banned cards directly.

Also, the same named 「BS17-073 Ardor Flame」, 「BS11-075 Totentanz」, 「BS04-102 Dream Hand」, 「BS02-106 Royal Potion」 will also be banned instead of being restricted to <1>.

「BS56-076 Oracle XVII Over Star」 can stall the game, extending the game until you are able to complete your loop; 「BS31-105 Substitution Technique」 allows you to use any card repeatedly. With the appearance of [The Burning Blade Flag Bearer, Saber], the importance of these 2 cards in a loop deck increases exponentially. Hence, they will not be restricted to <1> but instead banned directly.
