I actually don't run signets at all in my 540 unpowered and I've not felt a huge need to add any of them. As for what i'd include over Tezz I have yet to get that far into it and am unsure what i'd consider as options just yet. The rest of my section is Baleful Strix, Psychatog, Dragonlord Silumgar and Ashiok at the moment though.
So I have Tezzeret, Agent of Bolas in my Unpowered 540 cube but I am starting to feel like he is a tad out of place. Whenever artifacts gets drafted it's usually U/R. Does this guy really have to be around to support the deck if I don't have power or should I swap him out for something more universally playable?
With another 2 anthem effects added to black and white with the new Gideon and Drana I am wondering if it would be worth it to make a swap of Sorins from LoI to Solemn Visitor. I don't really want to include a second walker with the same type in a multicolored section so both isn't an option for me.
I've actually been wanting to add Awakening Zone for awhile just always forget to so this actually looks pretty interesting to me now. I'll probably throw it in for testing.
Not sure if I like it over Izzet Charm or Electrolyze. If I did add it my Izzet section would end up as stacked in 4 drops as Gruul but I am intrigued by this.
