If Bob Eubanks' Card Sharks were to come to Buzzr on January 4th, there probably may likely be promos for such show on Buzzr next week. Unless some promos appear on Buzzr in the days leading up to January 4th, or if there is official evidence on Buzzr's advance schedule, don't buy into such claims.
However, I bet if such version of Card Sharks appears on Buzzr, it will likely be from among the 200 episodes aired on GSN from 2010 to 2012, since GSN currently airs the late October 1986 to May 1987 episodes. I highly doubt we'll be seeing Buzzr's run of this series start in the middle of the series, otherwise GSN may not lease them.
Good thing I blocked Zach Horan on Facebook ages ago.
