I just played a pvp game in which my opponent used vampires, nightfall, devourer, and darkness pillar. not that strange.
however. it got to the point where every turn he would return to full health and every few turns all of his monsters on the field would die.
im hoping uits just a bug and that the other player was not cheating. His name was SolarRapier if that means anything to anyone. and if he sees this he should know im not accusing him of fowl play. just trying to make sense of what has happened.
