I'm looking for stuff to build a tempered steel affinity deck for legacy. I'm interested in the following cards:

4x Seat of the Synod
4x Ancient Den
4x Darksteel Citadel
4x Master of Etherium
4x Frogmite
4x Thoughtcast
4x Cranial Plating

I have plenty of stuff available to trade, mostly in Standard, and would be interested in setting something up! Take a look at my trade list if you are interested. If you want something in particular from the last iteration of Standard that's not on our list, let me know and I'll see if I can find one!

I'm looking for suggestions on what I can use to replace the Gloom Surgeons and Phyrexian Metamorphs. I often find my hand bloated due to these cards. The Gloom Surgeon ends up being fuel for my pod to generate a Geralf's Messenger, and the Metamorph turns into another potential Blood Artist 90% of the time, which (for me) doesn't justify the life cost to hard cast it.

I'm considering Dregscape Zombies, Bloodthrone Vampires, Mortarpods, or more Perilous Myrs to replace the Gloom Surgeons. I find the Myrs and Mortarpods to be particularly effective, though they are the only two cards I have any experience with.

I'm not sure what to do with the Metamorphs, but any suggestions would be greatly appreciated.
