Legion Loyalist maybe?

What is the overall strategy you're going for? If you want to abuse multiple combats per turn, take a look at @Mewgle's If You Want Peace, Prepare for War. It should give you some good ideas.

Unless your meta runs a lot of curses, consider cutting Witchbane Orb.

Other cards to consider cutting: Firemane Avenger, Sunhome Guildmage, Skyknight Legionnaire, Serra Avenger. These are all fine cards, but are easily overshadowed in EDH and can be cut if you're looking for cards to get rid of.

I also would not run the new Gideon, Champion of Justice. He is nowhere near as good as his counterpart and not worth a spot in your deck.

Good luck with your deck!

Creatures you can do without are both Akromas, they're just dudes with a bunch of keywords, same goes with Baneslayer Angel, Razia, Boros Archangel is far too expensive for what she does, Blade Splicer is too small of an effect without enough Golem tokens or blink effects, Ryusei, the Falling Star hits your creatures with his death trigger so is quite dangerous to have around. You don't have enough equipment to justify Stonehewer Giant. Sunhome Guildmage 's abilities are too expensive for what they do. Skyknight Legionnaire doesn't do anything at all for the deck. And Serra Avenger can be replaced with Serra Ascendant.

Other things that can come out that aren't creatures include Rage Reflection, it's outclassed completely by True Conviction. Gideon, Champion of Justice, and Elspeth, Knight-Errant aren't as good as their counterparts in token strategy, Gideon because he doesn't do all too much and Elspeth is better in a Voltron strategy.

Sunforger is one of the best things to run in Red/White. The +4/+0 is gravy to what other things it can do. However you will have to run a few Red and/or White instants. I'd recommend Swords to Plowshares alongside Path to Exile, Master Warcraft for combat control, Wild Ricochet for copy and redirect, and using Mistveil Plains to tie it all together.

Hope this helps.

Aurelia is perfect for some commander damage kills. Glory of Warfare can really step up her ability to slaughter your opponent. I'm a big fan of Inquisitor's Flail too. Trailblazer's Boots, Spirit Mantle, Holy Mantle, and Whispersilk Cloak can make her unblockable (and barring Reach, so can Skyblinder Staff). Totem-Guide Hartebeest and Steelshaper's Gift can get you the buffs Aurelia needs. Hellkite Charger + the Sword of Feast and Famine that you already have in there...you do that math. World at War, Waves of Aggression, and Relentless Assault build on what Aurelia already does. Argentum Armor on her can be brutal removal. Brass Squire can put things on her while saving precious mana. You could even run a lot more equipment and put in Puresteel Paladin.

Basically you should try out Voltron-ing Aurelia and swinging with her as much as possible and see how that works for you. Good luck! (TONS of great equipment out there.)

Oh, also, you have Boros Garrison in there twice. Oughtta free up a slot for you.

I wouldn't really use Spirit Mantle or Holy Mantle. Auras don't mix well with Equipment. Say Aurelia has Holy Mantle on her, you then can't put Sword of War and Peace or Sword of Light and Shadow on her because those give protection from White and will cause the aura to fall off. And not to mention you'll have to supplement both Auras and Equipment which will just take up space in the end. It's always just Auras or just Equipment. Never both.
