There is a card game called Yablon amongst other names, you can get info about it at
www.pagat.com which is a site devoted to card games.
As for poker variants: I will recommend Count Your Daimonds, it is five stud with whoever has the highest diamond count taking half the pot vs high hand taking the other half. You play it with Ace=14pts, King=13pts, Queen=12pts, Jack=11pts, and the rest at pip value.
