Spider-Man and the Thing are the stars of Marvel’s two team-up books, but they haven’t actually teamed up together. It makes sense to run the story in MTIO, since it didn’t sell nearly as well as Marvel Team-Up.
The two heroes are at a Renaissance Fair. After that, this story writes itself, doesn’t it? A “fake” magician becomes real because of some dark magic, blah blah blah.
It’s not bad, it’s just pretty predictable.
