I will start doing updates for booster sets and trial decks for Cardfight!! Vanguard. These post will contain information for the sets or decks with cards revealed from either card of the day on the official website or sneak peaks from the KeroKero Ace magazines.
This post is on a new trial deck, Descendants of the Marine Emperor. This deck introduces a new clan, Aqua Force. It is scheduled to be released in Japan on the 1st of August and contains a variation of 18 cards. There will be 3 shiny cards in the deck 1 which is RRR rarity and 2 of R rarities. The trial deck will also contain a first guide, a play book, and a play mat. Here's a poster for the trial deck from the official website.
