True my friend (Kkapoios). But as someone before me has stated "not everything that a character claims is always valid". Yet all the information we have about the the show's universe (or at least most of it) is through dialog between the characters. In this case: Most angels agree that Michael is stronger than Lucifer. Why is that? Because he is older and actually he has defeated him once. So far, so good. Yet we have seen cases when an "inferior" being could bind a "superior" one. Example: When Sam and Dean managed to bind Death. Another one was earlier when Lucifer managed to bind not only death but the other horsemen as well. So what if he knew a way to bind Michael as well but he just didn't have the chance to do it since Dean interfered and then he was imprisoned again. So my theory is that he has done something like that to Michael between seasons 5 and 7. Plus we still don't know the exact nature of magic or its full extent yet we have seen that magic can do "miracles" in the right hands and I think that Lucifer is more than proficient in that particular art.
