The 1986-1987 syndicated season of Card Sharks, hosted by Bill Rafferty, returned to Buzzr on Monday, October 22nd. It's on Monday-Friday at 4:30 pm EST. (Replacing the 1986-1989 CBS Bob Eubanks episodes of Card Sharks.) I also noticed that GSN dropped Eubanks CS from the Monday-Friday schedule (9:00 am - 10:00 am EST), so I guess it's MIA for now.
As far as Rafferty CS goes, they started with the September 8, 1986 premiere. From what I've read, the addition of the prize cards and the car game happens at the beginning of week #4 on September 29, 1986. (IIRC, the car game was added to the CBS Eubanks CS about a month later, in late October 1986.) I also understand that the last time Buzzr aired Rafferty CS, they only aired the first five weeks of shows (25 episodes) and then dropped it. Hopefully, it will last longer this time.
