Yeah that's happened to me in a few games. In other games I draw Destiny board and watch as the AI feeble attempts to kill me in five turns as the board spells out final. The deck I'm currently rocking with in game is a primarily Rock based game based around special summons, and effect cards. Optimally I can summon three monsters in one turn (play, special summon, Ritual) and it has happened. Fall back plan is Millennium Scorpion and the 'FEED ME MORE SEYMOUR!' plan that revolves devouring all his monster cards.
