The Uncanny X-Men #422

In "Rules of Engagement Part 2 of 2," the X-Men face escalating conflict with Alpha Flight over the safety of the students at Xavier's school, as tensions boil over into confrontation. With Sammy returned to his family in Canada and Polaris taking a drastic step by eliminating two members of the Church of Humanity, the team fractures further—Stacy X walks away, and Nightcrawler uncovers the first trace of the mysterious Draco. Written by Chuck Austen and illustrated by Ron Garney, with inks by Mark Morales and colors by JD Smith, this pivotal issue sees the team pushed to their limits, all under Philip Tan’s striking cover.
