Unlike the Start Decks that are made for new players, Trial decks are pre-constructed decks tailored for advance Buddyfighters, and thus contain cards that offer more complex gameplay and strategies.
The X Booster Pack Vol. 2 "Chaos Control Crisis" booster that launches on the same day as the Trial Decks, offers many cards that have high synergy with Darkness Dragon World cards in this deck.
"the Chaos" flag is used by Wisdom, a new character in the animation series. "the Chaos" being one of the few flags that enable you to play a mix of cards from different worlds, allows this Trial Deck to feature key monsters from different Worlds! If you are looking to form a formidable "the Chaos" deck, this Trial Deck will give you the power that you need!
