Been blasting through this over the weekend and my most recent round completed was an unlikely win against Advanced Citizen Dawn. The environment was dead set on getting Dawn to flip and only due to Citizen Truth being out did she flip back. Fortunately by the time she flipped only Citizen Anvil was in her deck of the Citiznes to deal damage and he didn't show up until she flipped back. After her flip she last only one more round after Tachyon finished her off with two fully powered Lightspeed Barrages.
