Card Appearances:Thunder End Dragon
- In episode 31, an unknown WDC Duelist uses this card during his Duel against Charlie McCay. After Charlie activates "Dream Dice" and gets a six as the die result for its effect, the ATK of all monsters controlled by the WDC Duelist become 0. "Number 7: Lucky Straight" then attacks one of the unknown Duelist's monsters. Charlie then activates the effect of "Lucky Straight" to roll a die and multiply the ATK of "Lucky Straight" by the result. Charlie gets a six, so the ATK of "Lucky Straight" becomes 4200. "Lucky Straight" then destroys its attack target and wins Charlie the Duel.
