In the near future, a battle card game called "Battle Spirits" has gained enormous popularity. Players of the game -- known as "Battlers" -- start duelings everywhere using their color-coded cards with different attributes, creating a "Sengoku (Warring States) period" for the game.
When Aichi Sendou defeated the evil Link Joker clan, the boy both proved himself as a top-notch Vanguard player and saved the world in the process. But now, for unknown reasons, Aichi’s very existence has been erased from the minds of all who knew him, and the rest of the gang no longer remembers their own friendships either. So when Toshiki Kai suddenly remembers his long-lost friend and rival, he’s determined to get to the bottom of why this happened and where Aichi might be hiding, even if he has to battle each and every one of his friends to remind them of the truth. With his new, mysterious “Legion” power that combines Vanguard units for a special attack, Toshiki will do his best to help the world remember Aichi.
I think you'll like Future Card Buddyfight if you liked Cardfight!! Vanguard: Legion Mate because both anime focus on cardfights. This is all just my personal opinion but I highly advise that if you watched one of these anime, you'll LOVE the other.
