Set after the X-Men went into reprints and before Giant X-men #1 made them legends, this book collects a guest appearances by individual X-men in Amazing Spider-man and the Incredible Hulk, and also multiple X-Men guest-starring in Marvel Team-up.
The comics are okay. Marvel Team-up #4 is probably the best story and the X-men do take the lead since Spidey's out of commission for most of the book. The Beast's solo series is not bad, but what he was going through felt very derivative of what the Incredible Hulk's set-up. Still, it's worth seeing in order to find out how the classic Hank McCoy changed to his more beastial form. Although his changing of color from gray to blue is not well-explained.
It's not terrible, but you can see why the X-men were in a no-man's land.
