List of great black jack players, but none of them were in the multiple millions several times consequtive league.

here is an interesting one, where missleading the casinos were just as important as counting cards:
"Kevin Blackwood has been quoted as saying that a good card counter will win between a quarter to one-third of his max bet per hour, so with a max bet of $1,000, he was probably earning around $300 per hour.
When he was concentrating solely on gambling, his day would usually start with a morning run (he ran track in high school and played basketball). He would then eat breakfast and head off to the casinos. While he would often play up to 8 hours at a time, Blackwood might spend as many as 14 hours total getting a feel for the casinos and the tables and looking for the most advantageous situations.
He would often take as much as $40,000 with him on his trips, with the rest being left at home or invested in the stock market. He would then cram up to $20,000 in a fanny pack and leave the rest in a safety deposit box. He normally expected to win around $2,000 per day, but these numbers could sometimes fluctuate to a win (or loss) of up to $20,000.
Kevinâs first order of business upon entering a casino was to circle around the pit and then stand behind a table, back counting until there was a favorable situation. He would then jump into the game and place a large bet. This was usually allowed, as pit bosses didnât want to chase away high rollers. He would then jump his bets up or down according to the count.
He would usually keep his sessions short in order to cut down on the chances of being discovered. He would run from casino to casino, often dressed in jogging attire (with his winnings still kept in his fanny pack)."

I think one reason why there are no multiple million winners is that the casinos usually smart up really fast and they share info with each other. That's why it was interesting how Johnson were able to take 3 casinos in such a short timeframe...
