It's funny how Marvel tried to push the Avengers as the main team but yet the X-Men have been outselling them and have better quality stories.
Once Fraction left Uncanny (horrible run) Kieron Gillen has made the book awesome to read but Greg Land ruins it with his art.
Uncanny X-Force by Remender is probably the best x-book to read right now even though the art in the last arc sucked. AOA Nightcrawler is a member on the team.
Wolverine and the X-Men is a fun read with characters like Kid Gladiator, Broo, Quire, Genesis, etc. make the book interesting.
the only tie ins for Avengers vs X-Men are..
Wolverine and the X-Men
I got to meet Brubaker last week during the AVX launch parties.
