As almost EVERYONE knows, lots of MTG sets are based of certain cultures from history and the world. for example...
Amonkhet: Ancient Egypt
Lorwyn/Shadowmoor: Celtic culture in general
Kamigawa: Japan and Shintoism
Tarkir: A mix of cultures of Central and East Asia (I could go on about this one)
Theros: Classical Rome and Greece
Arabian Nights: Take a wild guess.
Portal Three Kingdoms: Imperial China
Kaladesh: Steampunk India??? (I find the way they did the whole India thing underwhelming at best)
And soon Ixalan, which is Aztec/Mayan/Inca cultures from my guess. My problem with some of them (pretty much Kaladesh) is that the source material is kinda thrown in their for reference than anything. But I would like to know the opinion of other Cardsmithers than myself!
