Because I have nothing else to do:

1. Bobby Aka Dizzy (I dueled him several times and got pwned, the best I did against him was score 1 point ;o)
2. FireSworD (Skilled, active person, very difficult in a lot of levels)
3. Turtleslayer (Havent played him in a while (not since last year I think, actually) but he's a very good player and its fun to duel him)
4. CelL (Im putting him ahead of me because he owned me last JDC season. Once again I dont think I dueled him this year so I cant say how rusty he is)
5. BlurredD (Doesnt duel much, mostly idles, but deep within he shouldn't be underestimated)
6. Blacky (;D ;D ;D)/Skull (Also a good duelist who is rux in a lot of levels)
7.R3ptile (Very active person, duels a lot of people, and has a lot of skill/AvK (Havent seen him duel much, but he's ok from what I can tell)/Gummi (Completely pwned me in B1 and DW ;|)
8. Thunder (Very skillfull at a handful of levels, good teamplayer etc)/Enigma (Also very skillfull and great in team games)/Anakin (Havent seen him duel much but he's good in events and those types of things)
9. Jman FoR (He's alright in 2vs2s/3vs3s and pretty good in some levels)/Superjazz (He got a lot better since last season and shouldnt be underestimated)
10. Snooze (Also pretty good in duels and events)/ChavRash (I dont think I dueled him and barely ever saw him play, but he's also rux from what I can tell)

Anyways, this is definately more than 10, but I dont really care. I probably missed out a lot of people, for reasons of either forgetting they exist or not witnessing their skillz (Different time zones, perhaps?) enough, but whatever. Just because someone is listed underneath another in the list does not mean they cannot overcome them. The ranking thing is based on activeness, skills in open games/events, how they do in duels and team games and how wide their variety of levels gets to (i.e. a person really awesome in BBlair and Dist would be ranked under someone really awesome in BBSwing, Zaitox, and SBv2). So yeah. Have fun reading my (semi) biased list ;D.
