Allow me to add three games to the list of suggestions. I quickly read the last few pots of page 2 and skimmed page 3 so if they my suggestions have been mentioned before, take it as further support for cool games!
Card Game 1:
Citadels. Description from BGG, "Players seek to build a collection of districts worth from one to eight points. Once someone has built eight districts, the game is over after that round ends and the player with the highest total value wins. However to facilitate the process (and make the game interesting), players sequentially choose a character from a rapidly dwindling pool of eight each turn. The characters give players special abilities for the turn."
Card Game 2:
King's Blood. This game is similar to Uno, or other 'card runs-combo' games but you try to build royal family trees and score points, while also backstabbing other players through assassination and exile. Hopefully you don't mind the Manga/Anime art style.
Boardish kind of game played with cards 3:
Modern Art. A fast and fun game where you try to bid on pieces of art and try to get big pay offs for them later. Very fun.
