At the beginning of the series, Aichi is revealed to possess a Royal Paladin deck. In his final confrontation with Ren, Aichi adjusts his deck so that Blaster Dark is mixed in with his Royal Paladins so that he could use Majesty Lord Blaster's abilities to the fullest.
Seeking more power, Aichi visits the card shop PSY, where he is confronted by Ren Suzugamori. Ren gives him the Shadow Paladin deck, which completely corrupts him and causes him to abandon his Royal Paladins in favor of the new clan.
In the Season 2, Aichi is forcefully given a Gold Paladin deck to use instead of his Royal Paladins, with Blazing Lion, Platina Ezel as his signature Crossride unit.
In Season 3, Aichi continues to use Gold Paladin as his main deck. His deck consists of the Liberators series, many of which were originally Royal Paladin units.
After the High School VF tournament he modifies his deck to include Wolf Fang Liberator, Garmore in order to fill up his field with its multi-calling skill and to return triggers back to the deck.
Under the influence of the seed, Aichi uses a Link Joker deck based on the Star-vaders. His ace unit, Star-vader, Imaginary Plane Dragon's Legion skill allows him to lock his opponent's rearguards, restricting their movements during their turn.
In episode 193, he uses a different Link Joker deck during a cardfight against Kai. His new ace unit, Star-vader, Blaster Joker's Legion skill allows him to lock all of his opponent's units at once. It also retires his opponent's Legion mate, preventing them from using their vanguard's Legion skill in their next turn.
Many years later, during NEXT, Aichi returns with a brand new deck. This deck features the return of Blaster Blade and contains his new avatar, Blaster Blade Exceed.
