Explanations are, of course, optional.
In no particular order...
1. Banockles: Incredibly competitive classic speed player (flat rate/no cards). His sheer will to win managed to either defeat me or simply stalemate me into submission. Top player.
2. Jade Empire: Still working this guy out, but is without doubt one of those no cards players who are always just there.
3. Railfrog: Patient beyond any normal level of patience. My pal manwiththeplan alerted me to his talents. Completely stalemating eachother in two games so far and no end in sight...
4. Fruitcake: While I have yet to join his school(

5. Gambler21210: That rare thing, an exceptionally attacking no cards player who knows when to wait it out as well.
There are many others I also respect (those currently playing my private 2.1 8 mans know who they are) but these are the five no cards players who have stood out for me.
Players of all styles are of course welcome to be listed here.
