Harmony PCG
Two Argentinian blokes who called themselves Silly Mare Games (creators of Stroll) were playing Tales of Eternia's "WHIS" minigame when one of them decided that it needed more ponies, and recreated it in Game Maker. It has a pretty main menu and nice music, but unfortunately I can't exactly review it since I'm not sure how one should grade a card game. Kind of a shame that it doesn't have multiplayer, but hopefully the developers decide to implement it fairly soon.
Oh yeah, and it works well enough in Wine, if agonizingly slow. As with all Game Maker games you should install directmusic and dsound via Winetricks/PlayOnLinux in order to have working audio, but since it runs so slowly on Linux you might want to skip the game altogether. Then again, I did manage to complete the entire game of SuperTux on my old Linux box while running the game at about 5fps, so don't let extremely low framerates stop you!
