My list isn't far off that - gotta admit your advice helped me shape the list bigtime. Ta for that.

I've been playing with this deck casually too, amongst friends who have vintage/legacy decks, and I've been playing with a few additional cards that would rarely ever see tourney play.
The one I've been surprised by the most is Salvage Titan as a singleton.
I've found it quite useful post a board wipe or an artifact wipe.
I haven't tried playing with it in a tourney against unknown opponents, but it was quite useful when I drew/found it with Tezz - post wipe.
I should explain, once I've emptied my hand, I play expecting the wipe to come (DoJ, BSZ, Terminus etc.) so I always hold back a few cards that can be potential fuel for it if I have it in hand. I also play a full 4 Darksteel Citadel.
Have any of you tried playing with the Salvage?
