I'd advise you to just build my deck. Specially some cheap inclusions but very synergysing like
Empyrial Plate. Also I'd rather have a big focus on equipments if you can afford them than mix with auras, since they don't synergise with many other good enablers. You use some super good and expensive cards but then you leave some extremely underpowered things like the Ring equipments,
Mask of Avacyn,
Kor Cartographer, the
haunted cloak, temur battlerage (which only provides double strike), danitha, who doesn't do much if you don't want to equip her as every equipment should go on wyleth. Also I'd put out every tapped double land if I could have an untapped one for some more, and also take out the irrelevant colorless utility lands like
encroaching wastes or myriad, which we'll not probably use, as we want to win fast. Finally, i'd add every "equipper" guy I can find to avoid paying all the mana equipping costs, better than the 1 mana we save with Danitha. Good luck!
