Yaffa's Doctor Strange series ran for seven, possibly eight issues.
At least two retitled editions were issued from this series:
Mystic Arts Master
These are the only two I have seen.
There may be a retitled edition of Doctor Strange #2, which was recycled as #4 in the series, but given this triple-dipping occurred with #1, it's possible the pattern was repeated.
I also wouldn't be surprised to see a subsequent edition of Doctor Strange #5. TBA.
