Uncanny X-Men #21

Cyclops and Magik showing up at the Jean Grey School for Higher Learning turns out badly for everyone as some mysterious force forces both mutants to lose control of their powers, and Maria Hill and the fake Dazzler's attempt to show up and take custody of Cyclops ends with S.H.I.E.L.D. losing control of the Hellicarrier and attacking a school of students - much to the glee of the mysterious figure who continues to watch from a distance and make his puppets dance.

The issue's back-up story takes Magneto back to Madripoor (for unexplained reasons which only marginally really fit his current path in his own ongoing series). There the team's former member discovers the true fate of Dazzler at the same time Beast makes a discovery concerning the identity of their unseen enemy. With those insights and Hill's realization that someone has been forcibly maneuvering a war between the X-Men and S.H.I.E.L.D. should hopefully lead to a big reveal and some real answers beginning next month. Worth a look.
