Llyranor said:How many cards are there in total, and how diverse are they (as opposed to just small variants of each other)?
There are 122 cards in total. They're split into 5 different color types (like Magic, except its 4 colors and colorless), and each color category has several characters. For each character there are different cards representing different skills and attacks. Everything is pretty varied and it's definitely not something tacked on.
