So I was reading some forums of people speculating how the exotic Titan gauntlets Thagomizers might be obtained. https://www.bungie.net/en/armory/Detail?type=item&item=155374076&itemname=Thagomizers Many players believe that Primus Ta'aun (boss on "Regicide" mission before Oryx) will have something to do with it, as he wears the Thagomizers, or a larger re-skin of them anyways. So I had some Three of Coins from Xur and loaded up Regicide. I used 7 three of coins and when I killed the Primus he dropped not one but TWO exotic engrams. One of them was a chest engram and the other was amazingly a gauntlet engram. I went back to the tower and disappointingly, they decrypted into Immolation Fists. Just thought I would share that to let people know I tried this method so we can scratch it off. We might have to wait until that mission is a daily heroic or it might not involve Primus Ta'aun at all.
