I am at stage 23 and I have to win with a deck out. I have done it around 4 times and it still won't complete the mission why? Does anyone know? I have tried it in the world and ring.
Are you sure your opponent's deck has no card, and not your deck? Deck Out means your opponent has no card to draw during your opponent's Draw Phase, meaning even if your opponent's deck is already empty during your turn, you still need to end your turn first.
Yeah, what you are saying is exactly what I have done. I have also tried ways to make the opponent run out of cards faster, and still, it won't complete the stage mission.
Are you in the correct world? You must be in the same world (DM, GX) that requires this mission. Also, at the end, during the Duel Assessment (those points with the rewards), does it say something like "Deck Out Victory"? If it doesn't say that, then you're doing it wrong.
