Yu-Gi-Oh! 5D's - Season 1 Episode 10 The Lockdown Duel (2)

Yusei is caught in Armstrong's trap - not only is he forced to discard ten cards each turn, each Life Point lost also delivers a painful electric shock. Armstrong has disabled the electric current to his own Duel Disk, and thus does not feel any pain, until Alex breaks into the control room. He starts the current flowing again, but Armstrong just gets back up and keeps going. Despite the overwhelming odds, Yusei is able to pull through and win the duel. He is allowed to leave the prison.
