Thanks for the responses, guys.
I watched your replay, Ancengal, and I think I get how Ghost Wheels works a bit (not that I can do it). I have been using practice mode a bunch, but it looks like I need to just keep plugging away.
Suikama, I get the idea, but it doesn't seem to work in practice. It seems random whether or not the new set of wheels is aimed where I was or where I am. I think it's something like I'm dodging too early to the side. Either way, it looks like I'm just gonna have to resort to bombing it. I have too much trouble checking where the ghost wheels are coming from while still trying to dodge the other shots, which is weird, since I have no problem on Chen's final card in PCB.
The problem is that if I bomb the last three attacks, I will (obviously) not have any power at the start of stage 6, which is very bad. That said, I think I need to figure out the non-card. It seems to be based around placing yourself in-between two of the ghosts, waiting for the lull, and doing it again.
Ah well. Practice, practice, practice!
