I don't have Tichu otherwise I'd try it out as I'm always interested in two player variants.... But hopefully more people will find it now! Hope you continue to enjoy using BGG there are all sorts of fun helpful things to eventually find while exploring
You can play Tichu with a standard deck of cards. Just mark the 2 jokers and the other 2 garbage cards with DOG, PHOENIX, MAHJONG and DRAGON. It's kinda ghetto but it gives you a good idea if you'll enjoy it or not.
