That's his lazy way of saying "the pictures are on the cards, so I don't have to do full page drawings."when he mentions that the cards are part of the comics, what does that really mean? Do you have to collect all the cards and arrange them in a way where you can read them liiiiike a comic? Can you cut the pictures out of the cards and puzzle them together to make a complete comic page????
This CWC we're talking about, like he can try to make a puzzle that requires patience, thought and planning into it.
