In playing on the Dueling Network site I discovered an amazing combo done with Ghostricks that you would never even imagine, or even think of using. The combo I am going to reveal is very unique in that is unexpected. What I am talking about is Mystic Swordsman level monsters, but to be exact would be Mystic Swordsman LV4, and the continuous trap card Ghostrick-Go-Round. Now Mystic Swordsman LV4 states that he has to be set before he can attack. Ghostrick-Go-Round works around that. Since you cannot set and flip up the same monster in the same turn by itself, you can target that face-down card with an effect and flip it face-up. With Ghostrick Witch face-up on the field use her effect to change one monster your opponent controls to face-down defense position. Now you can attack with Mystic Swordsman LV4 and use his effect to immediately destroy the face-down monster it attacked during the start of the damage step, which cuts out the damage step.
I saw this being played and the results are amazing!
