You're right, the MAO is a pretty elaborate set. In a nutshell, most of it is straight up martians: the base set, a variety of subsets, as well as bonus cards/kickstarter extras. There's also a Dinosaur Attacks subset and the "Attacky Packages" subset, which is a bit of an anomoly since it combines Wackys and martians! I tried to tie the two together as much as possible, but I'll leave it to collectors to decide if it's more on the Wacky side or more on the martian side! In any event, I hope you enjoy it! It certainly was fun!
