Card Games Classified by Mechanism

I think this is a neat way to discover new card games

pagat.com in general is a treasure worth exploring, but I love this classification index. Personally I love shedding/climbing games more than most other styles

Haggis is a newer addition to the climbing/shedding category (tho it is 10 years old now), uniquely filling a slot for a good 2 player version (went to market to add a 5th suit giving you access to the 3 player variant)
