The Microsite for DP25 has gone live, with some additional details!
The overall description confirms that included duelists will indeed get 7 new cards each.
The section on Ruri’s cards confirms only 2 new “Lyrilusc” Xyz monsters, along with support cards focusing on rapid development and deployment of your strategy, replenishing the Xyz Materials of your Trump Card, and aiming for big ATK boosts. Some of these we may have already seen.
The section on Sherry’s cards, alongside the currently known info, mentions a new Continuous Trap that not only enables your strong points, but also helps disrupt the opponent.
Thank you to Ark for the translation!
