I have the following appearances by Strange around this time:This is as good a place to ask as any: What's Dr. Strange, Wong, and Wolverine's "before" and "after" for ASM #555? I know placement is kind of wierd due to the whole "Dr. Strange has left the team" routine...
FRIENDLY NEIGHBORHOOD SPIDER-MAN #24
NEW AVENGERS ANNUAL #2
GIANT-SIZE ASTONISHING X-MEN #1 ("I'm not at my peak")
FANTASTIC FOUR #556
FANTASTIC FOUR #557
FANTASTIC FOUR #562
LAST DEFENDERS #3 (paraphrasing: “I'm still not ready with my hands in this state and my mystical energies at an all-time low”)
AMAZING SPIDER-MAN #555 -- FB
SECRET INVASION #8 -- FB
NEW AVENGERS #51
Then there's Strange's appearances in AVENGERS/INVADERS, where he uses his "sorcery supreme." They must occur after after ASM 553, since a DB issue in A:INV 2 notes a Crowne-Hollister debate. And ASM 555-FB occurs only two days after ASM 553. So is Strange "partially powered" in A/INV?
