War Room is already in the deck.
Commander's Plate is killing me that I can't find room for it. because that would be amazing in this deck. I may find a spot for it, but I already have tons of equipment with very specific abilities. Notably, I have the Swords of X and Y, that only gives me protection from 2 colours instead of the 4
Commander's Plate would give, however they have two abilities that trigger when it deals combat damage and Balan gives me double strike and so double the triggers. For the moment I prefer that, but we'll see.
Seraphic Greatsword is neat but conditional, which I hate. Whenever there's a condition on a card, fate will find a way to screw you over. The only way to avoid that is by not having that card at all, because it will always happen at the worst time. Speaking of getting screwed over by a card, Rebbec is extremely cool, but I have
Etched Champion and
Stuffy Doll that I need to equip things to and I can't with Rebbec out. It will be great in a lot of situations, but it can also work against me. I'm already nervous with my
Indomitable Archangel, but at least with that my artifacts are protected by all targeted removal, not just ones that can get around the mana costs.
Court of Grace: not powerful enough with the central strategy of my deck, plus puts the Monarch into play which will make me a target and help my opponents, two things I don't like.
Ardenn is a card I considered, but ultimately don't have room for, especially considering Balan can equip everything for 2 at instant speed, so it's good but a little redundant.
Archon of Coronation, super cool card but refer to the above regarding the Monarch mechanic. Also, 6 mana is extremely expensive for this deck and doesn't contribute directly to fulfilling this deck's
game plan. Akroma is even more expensive and also doesn't contribute directly to the
game plan (which is to strike with Balan at an opportune time with deadly equipment).
Akroma's Will is crazy good, but it doesn't do anything that my suite of equipment doesn't already do, and my deck benefits from equipment. I would love to fit this card into my Aurelia deck somehow.
Slash the Ranks is an excellent suggestion and fits super well into the deck. I'd rather have mass removal that will take out my opponent's commanders, however. I did consider replacing
Divine Reckoning, but it's cheaper and has flashback. I also considered replacing
Single Combat, but having to sacrifice creatures is far more powerful than destroying them, especially since Slash lets you
regenerate.
