idk why so many people whining about this great event. If you have a decent synchro deck, it only took you 3 games at most to finish it by yourself. That's why this called as raid duel: if you only have crappy deck, you don't need to finish the game by yourself. there's so many duelists out there (with more efficient deck) will help you to finish off Ccapac Apu. Git Gud, whiner scrub ;)
It's not a great event, tbh. Frustating for new players, indeed. But i don't think you have to pay money for this event. Psychic hyper blaster + Power Guardian do well in this event. Ez 30-40k damage per game.
