Tanking trinketsFollow

I have a question about the list of tank trinkets on the Lvl 70 gear list sticky. Below is the trinket list:

1. [Gnomeregan Auto-Blocker 600] - Sold by G'eras for 41x Badge of Justice.
2. [Gnomish Poultryizer] - Made by an engineer.
3. [Goblin Rocket Launcher] - Made by an engineer.
4. [Commander's Badge] - Quest reward from Hail, Commander!
5. [Argussian Compass] - Drops from The Black Stalker in The Underbog (Heroic).
6. [Adamantine Figurine] - Drops from Blackheart the Inciter in Shadow Labyrinth.
7. [Brooch of the Immortal King] - Drops from Terokk in Terokkar Forest.
8. [Dabiri's Enigma] - Quest reward from Dimensius the All-Devouring.
9. [Figurine of the Colossus] - Drops from Warchief Kargath Bladefist in The Shattered Halls.


I've had trinket 8 for a while now, but just as the Adamantine figurine (6) dropped I found the last card I needed for the Furies Deck. Where does the trinket it creates fit on this list? Is it worth it to replace 6 or 8 over it?

Thanks
