Yu-Gi-Oh! 5D's

Episode Synopsis

Yusei, Sherry and Bruno infiltrate the Ener-D Express Headquarters, disguised as representatives of Bolger's company. There, they are shown a new Infinity shaped Ener-D reactor by Clark Smith, which is supposedly designed to allow Turbo duelists to travel through wormholes. Wanting to learn more, they sneak into Clark's office to obtain an access key for Level 10 clearance. When Clark returns, Yusei holds him off by challenging him to a duel with some new rules Clark throws in whilst Sherry and Bruno head for the restricted area. Clark's duel requires players to declare the type of card they want and successfully pick the right one in order to use it. However, Clark gains an advantage by cheating using his glasses. Realizing this, Yusei manages to summon Stardust Dragon and defeats him. However, Clark had already figured out their identities and sets off the alarm.
