Ep. 20: Kamui tests trio's teamwork through exercises and a special cardfight against Team Trinity Dragon
Aired on March 15, 2015

To prepare for the regional Vanguard tournament, Kamui forms an unlikely team consisting of Chrono, Tokoha, and Shion. He evaluates their coordination through various exercises, but the trio displays no harmony. Kamui then challenges them to a special cardfight against Team Trinity Dragon, where members switch roles after each turn. During the match, Chrono, Tokoha, and Shion frequently argue over their differing strategies. Team Trinity Dragon wins due to their excellent synergy, leading Kamui to conclude that their unnamed team has no hope. Determined to prove him wrong, despite his claims being a ruse, the three resolve to make their team successful.
