A lot of cards you're running are WAY too slow for 1v1. Many also don't do much to serve your theme. I would cut all of the artifact ramp (other than maybe Sword of the Animist), Staff of Nin, Avacyn, Elesh Norn, Eternal Dragon, Raksha, Sunblast Angel, True Conviction. Conqueror's Pledge, Austere Command, Martial Coup, etc. -- basically anything with CMC above 5 is a good rule (would be fine in a green ramp deck or a very control-oriented deck but not here).

In exchange, you want more cheap equipment (Leonin Scimitar, Bonesplitter, Shuko, Bone Saw, Explorer's Scope, etc.) and some that synergizes well with Kemba (Champion's Helm, Hero's Blade, Mask of Avacyn, etc.). You also want more targeted removal and ways to deal with opposing threats, such as Journey to Nowhere, Last Breath, Revoke Existence, Leonin Relic-Warder, etc.
