All 10 Duel Ranks before Kaiba

Obtain all 10 possible ranks in duels.  Each rank must be obtained on a different duelist.
Kaiba must not be defeated.
You may not fight any optional duelists in Egypt 1 (besides DMK).

Free duel is allowed.  The first time you obtain each rank, you will lock that rank and that duelist from being counted again.

Example situation:

You start by going to DMK and obtaining a B-POW, this locks in B-POW and DMK.
Do a second DMK and get an A-POW.  This does not count for the goal since DMK has already been used.
Move on to Rex campaign and get a B-POW.  This also does not count for the goal since B-POW has already been used.
Weevil campaign A-POW, locks in A-POW and Weevil.
Back to Rex free duel for S-POW, locks in S-POW and Rex. (and so on)
