Agreed that something particularly impressive can be hard to get, especially when you really want it.
Sorry if I sounded particularly harsh - I thought that you continued a discussion from previous thread which should have ended after KO's post.
As for Gandalf's question - while renaming could be somewhat useful against unwary player (and for this you can check a list which is here somewhere), the specifics are such that there are no titles present for low Astral which can't be present for high one afaik. The only possibility I see is to have low Dominion which limits a number of titles, then with, e.g., extreme scales you can have just one Astral title which leaves your opponent guessing whether you actually have only low Astral - or you are just masking it!
As for (renaming?) trick being banned in MPs - don't think so. It's quite easy to see through, after all.
