Sorcerer remain a relevant meta comp thanks to the Twisted Fate Legend. In fact this setup was so powerful Riot had to include some additional changes to Patch 13.21 to prevent this comp from taking over the meta.
The main idea is to run a double Stoneplate Taric isolated in the frontline to maximize defensive values, give him QSS to ensures he always gets his cast out and doesn't get kicked away against K'Sante. In the backline you are running Silco as main carry who also helps to keep Taric alive.
In late game you add Shen to help with the frontline and itemize either Ahri or Vel'Koz*3 as an additional carry in late game.
