Halloween Trickster confuses me. So the double ATK increase means that Pumpking's effect maxes out after 3 standby phases (3x100x2=600) or does it's ATK increase by 1200 (600x2)?

is Halloween Manor and Halloween Trickster just supposed to decrease the time it takes to do Pumpking, ruler of Halloween's effect.
you could just put on the card the ATK increase only last for so many turns sorta like Pumpking the King of Ghosts effect
