This archetype been around in throne for a long time, there's very little need to explain how this deck works; its been one of the best ladder decks in throne. I hit Masters with it this month, which isn't a surprise with this deck. If you have a life and not aware of going ons in eternal discords, 2 cards in the most common lists, Grodov's Stranger and Speaking Circle, are controversial among dedicated players.
So this list doesn't run either. I use Gates of Hope in place of Circle; I'm really not sure about this card, its really just a 5 mana "heal" 5 + draw and/or stun a lot of the time. If you actually finish the agenda yes your high armor weapons have synergy but those only happen in a minuscule of games.
You could go even further and cut Coveted Gemstones for Crack the Earth and remake your market around that as some suggest, but I still find playing the cards only in a Coveted Gemstone market more satisfying and more fun.
I love Sword of Unity, I love Orene's Scepter, I find it fun.
