With the recent patch, Inscription is once again about to make another trinket. This one, however, doesn't require you to collect up a pack of cards that are pure chance.
For 10 Ghost Iron Bars (or 20 ore) you can make a Crafted Malevolent Gladiator's Medallion of Tenacity (or as I call them, GOLD).
These trinkets cost about 50g each to make, depending on the server you are on of course. I churned out four of them to see what kind of profit they could make me.
And four sold within a day and a half. For 500g each. Just to put this into perspective, for each Living Steel you use 60 bars. That's six trinkets, which all see for 500g.
Quick math time:
500x6= 3000g minus the 5% AH cut of 150 gold and you make a hefty 2850g AH return and 2550g Profit.
Of course, this is dependant on realm but that's basically the gist of it.
Keep on auctioning,
