Cardfight!! Vanguard - Season 3 Episode 13 Powerful Fighter at Fukuhara High

After Naoki makes another offhand comment towards Suiko, the two start their cardfight. Suiko criticizes Naoki for being a good but uninteresting fighter. He tries to prove her wrong when he activates the Limit Break of his new ace card: Armor Break Dragon. At the cost of discarding three cards from his hand, Naoki not only eliminates Suiko's front-row rear-guard units, but he also increases Armor Break Dragon's power and critical value to unbelievable heights. Despite this, Suiko defends against Naoki's attacks with almost all of the cards in her hand. On the following turn, Suiko wins the game with Chief Nurse, Shamsiel by moving cards to and from her damage zone thus increasing most of her units' power. Afterwards, Naoki apologizes to his friends for his loss and realizes how weak he actually is. Shingo cheers him up (although with some harsh choice of words) and says that he'll train Naoki to become stronger.
