These issues are full of transitions. A new creative team on Exiles (boobs and Austen), a loooooong transition before we get the master back on Excalibur (Alan Davis), What the F is happening on Generation X (Lobdell just acting to leave?), and a new team member of X-Factor (Guido becomes Strong Guy)
It's Exiles (2001) #26, Excalibur #25 (1988), Generation X #14 (1994), and X-Factor 72 (1991)
