As far as Muzz goes, we ave to get the build to... I think it was Ashes 2 Ashes 2003, where Sacred and El Luchador Magnifico were feuding over the World Championship. During the build, Sacred snatched the title from ELM, doing what was as I recall a very interesting storyline about adjusting his wrestling style to deal with ELM's more aerial style (which means we need to add at least one of the build matches that didn't involve ELM). There was much rejoicing when he did about how the Australian Glass Ceiling had finally been broken.
Frankly, the majority of Sacred's stuff is DVD-quality, so barring any other in-ring storylines, we'd want to grab the promo storyline and some of the matches surrounding it in which his wife died, which presented sort of a revolution for the character.
Unfortunately I'm working from memory here, so I don't have links available.
